Sandy works at a clothing store. She makes $8 per hour plus earns 10% commission on her sales. She worked 70 hours over the last two weeks and had a total of $1,612 in sales before taxes.

Which of the following is closest to how much she will earn in hourly wages and commission for those two weeks?
A.
$721
B.
$560
C.
$161
D.
$217

Answers

Answer:

A

Step-by-step explanation:

First, I'm going to work out the hourly wages for the 2 weeks.

$8 x 70hours = $560

(8 x 7 = 56 x 10 = 560)

Next, work out the commision.

10% of $1612

1612 ÷ 10 = 161.2

Finally, add together both the hourly wages and commision.

161.2 + 560 = 721.2

Round it down to a whole number.

721 , Add on the dollar sign.

It's answer A, $721.

A. 721
I’m pretty sure it’s 721$

Question about finding intercepts from a table. Hope someone can answer!

Answers

Basically you have to use the table to find the equation of the line, then plug in a point into x and y and the b you will get is your y-intercept.

Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:

1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)

2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.

Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)

Now that you know m, your incomplete equation will be this:
y=2x+b.

Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)

Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

Question 1
A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?



__ miles in one hour
pls no links ty

Answers

The truck driver can drive 64 miles in one hour.

Distance covered by the truck driver in 45 minutes = 48 miles

Distance covered by the truck driver in 1 minute = [tex]\frac{48}{45}[/tex]

                                                                                 = 1.066 miles

Distance covered by the truck driver in 1 hour i.e. 60 minutes = 60 × 1.066

                                                                                                      = 63.96

                                                                                                      ≈ 64 miles

Therefore, the distance covered by the truck driver in 1 hour is 64 miles.

-7 – 2 =
12 + (-4) =
-8(-6) =

18/-3=

Answers

Answer:

-5 , 8 , 48 , -6

Step-by-step explanation:

-7- -2 = -5

This complies with the rule that 2 negatives make a positive.

12 + (-4) = 8

You just ignore the brackets.

-8(-6) = 48

The -8 next to the bracket with no symbol means you need to multiply, and again 2 negatives make a positive.

18/-3 = -6

As the 18 is not negative, but -3 is, the answer is also a negative because one negative and one positive make a negative!

Hope this helps and have a good day!

The answer would be 1. This is because if you do this equation for every row in the table it would always equal y. 1/2x (x divided by 2) would always equal 2 less than y. There is no unit rate in this problem because it is not proportional.

Find the total cost with tip.

Markup (tip $) = percent markup (tip %) x original cost ($)

Total cost = original cost + tip


Mr. Smith goes out to eat for his birthday. The total bill is $122.50. If Mr. Smith leaves a 20% tip, what is the tip amount? What is the total cost of the meal with tip included?

The tip is: $_________

The total cost of the meal is: $_________

Answers

Answer:

$147

Step-by-step explanation:

so to find 20% I usually divide the original cost by 100 to get 1% then multiply that number by 20.

in this case 122.50/100= 1.225, 1.225x20 = 24.5

24.5 + 122.50 = 147

Step-by-step explanation:

First you need to change the mixed fractions into improper fraction which is 38/6 and the other fraction turns into 3/2 now since the question was about multiplying we multiply. So there are numbers that can be reduced like 3 divided by 6 and 38 divided by 2. So now that there are simpler nmbers that cannot be reduced more we multiply and we get 19/2 which if you wanted as a mixed fraction is 9 and 1/2.

Jose goes out to lunch. The bill, before tax and tip, was $10.45. A sales tax of 8% was added on. Jose tipped 17% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.

Answers

$13.20 $10.45x1.08=$11.28 $11.28x1.17=$13.20
ANSWER: $13.21

Find 8% of 10.45 then add the answer to 10.45 to get how much it cost after the sales tax.

8% of 10.45 = 0.836

Add 0.84 to 10.45

The answer is 11.29

Now take 17% of 11.29 and add it to 11.29. We are taking 17% of 11.29 because it said he tipped after the sales tax was added.

17% of 11.29 = 1.92

11.29 + 1.92 = 13.21
