1. Jasmine is 5 years younger than twice her sister's age. If Jasmine is 39 years old, how old is her sister?
Let J be Jasmine age and S the sister's age. Then, we have
[tex]2S-5=J[/tex]this equality means Jasmine is 5 years younger than twice her sister's age. Now, we also know that J=39 years then by substituying this value into the last equality, we have
[tex]2S-5=39[/tex]and now, we can solve this equation for S. First, we must move -5 to the right hand side as 5. It reads
[tex]\begin{gathered} 2S=39+5 \\ 2S=44 \end{gathered}[/tex]and finally, we obtain
[tex]\begin{gathered} S=\frac{44}{2} \\ S=22 \end{gathered}[/tex]therefore, Jasmine's sister has 22 years old.
Wendy is paid $9 per hour and plans to work between 20 and 25 hours per week. Identify the independent and dependent quantity in the situation. Find reasonable domain and range values.
The domain of the given question is; 20 to 25.
If she is paid $9 per hour, the range is; $180 to $225.
How to find the domain and range?The independent quantity is defined as the quantity that causes a change in the dependent quantity.
Now, In this question, the defined quantities are hours worked and weekly pay. Applying the concept of independent and dependent quality, the number of hours she works causes her weekly pay to change. This means that hours worked is the independent quantity and weekly pay is the dependent quantity.
We are told that she plans to work between 20 and 25 hours. This means that;
The domain is 20 to 25.
Now, as she is paid $9 per hour, this makes the range;
9(20) = $180 to 9(25) = $225.

A supermarket sells 500g pots of yoghourt. There is a special offer on yoghourt:
Buy 2 pots and get a 3rd one free!
A week later, the price of a single pot of yoghourt is still the same, but the offer changes to:
Buy 1 pot and get a second one half price!
Is the second offer better than the first? Show working to justify your answer.
The first offer is better from the perspective of a customer but the second one is better from the perspective of a seller.
Here we have different 2 cases, and to find the answer we have to follow a few steps.
First of all, we should simplify these two cases and will try to give them a proper equation format.
Let's assume the price of each yogurt is $x.
Therefore the total price of 2 pots is (2× x) = $2x.
But the condition is if we buy 2 pots, get the 3rd one for free. So, we can purchase a total of 3 pots at the same cost.
∵ If 3 pots cost $2x, then the average cost for each pot is 2x/3 =$0.67x
( average value of each unit = Total value / total unit )
In the second case, if we buy 1 pot we can get the second one at half price.
Therefore, the total price of two pots is, ( x + 0.5x ) = $1.50x
∵ If 2 pots cost $1.50x, then the average cost for each pot is 1.50x/2 = $0.75x
( average value of each unit = Total value / total unit ).
The price of yogurt per pot in the first case < The price of yogurt per pot in the second case.
As $0.67 < $0.75.

What is Probability?Probability is a branch of mathematics concerned with determining the likelihood of an event occurring. Probability assesses the likelihood of an event occurring and is equal to the number of favorable events divided by the total number of events.
Given:
Number of times Aaden performs the experiment = 31 times
A strawberry chew was selected 4 times.
An apple chew was selected 7 times.
A watermelon chew was selected 20 times.
So,
Probability of selecting a strawberry chew = 4/31
Probability of selecting an apple chew = 7/31
Probability of selecting a watermelon chew = 20/31
So, the probability that the next chew Aaden removes from the bag will be a flavor other than apple i.e. it can be strawberry or watermelon chew.

A farmer needs to enclose three sides of a garden with a fence (the fourth side is a river). The farmer has
30 feet of fence and wants the garden to have an area of 108 sq-feet. What should the dimensions of the
garden be? (For the purpose of this problem, the width will be the smaller dimension (needing two sides);
the length with be the longer dimežision (needing one side). Additionally, the length should be as long as
possible.)
length×width = 108
length + 2×width = 30
length = 30 - 2×width
using that in the first equation
(30 - 2×width)×width = 108
-2×width² + 30×width - 108 = 0
the general solution to such a quadratic equation like
ax² + bx + c = 0
is
x = (-b ± sqrt(b² - 4ac))/(2a)
so,
width = (-30 ± sqrt(30² - 4×-2×-108))/(2×-2) =
= (-30 ± sqrt(900 - 864))/-4 =
= (-30 ± sqrt(36))/-4 = (-30 ± 6)/-4
width1 = (-30 + 6)/-4 = -24/-4 = 6 ft
width2 = (-30 - 6)/-4 = -36/-4 = 9 ft
for width = 6 ft
length = 30 - 2×width = 30 - 12 = 18 ft.
for width = 9 ft
length = 30 - 2×width = 30 - 18 = 12 ft
given the request that the length sound be as long as possible,
width = 6 ft
length = 18 ft
is our solution.
Dominique paid $15.50 to join an online music service. She purchases 10 songs each month at a cost of $0.99 per song. Dominique thinks that after 8 months, she will have spent around $75.00 total. Is Dominique's estimate reasonable?
If she thinks that after 8 months, she will have spent around $75.00 total. Dominique's estimate is not reasonable?
Determining whether the estimated amount is reasonableWe have to make use of the given data to find whether amount of $75 which she estimated that she will spent after 8 months is reasonable
Total cost:
Total cost =$15.50 + 10 × $0.99 × 8
Total cost = $15.50 + 9.9 × 8
Total cost = $15.50 +$79.2
Total cost = $94.7
Hence,
$94.70 ≥ $75.00
Based on the above calculation the amount she estimated is not a reasonable amount because the total cost is greater that the estimated amount.
