Use your choice of equal values, substitution, or elimination to solve the
following System of Equations, and show your work.
i are running a concession stand at a basketball game. You are selling hot
dogs and sodas. Each hot dog costs $3.00 and each soda costs $2.00. At the
end of the night you made a total of $213.00. You sold a total of 87 hot dogs
and sodas combined. You must report the number of hot dogs sold and the
number of sodas sold. How many hot dogs were sold and how many sodas
were sold?

Answers

Answer 1

Answer:

For this scenario, I used the elimination method. Organize the equations, so it's easier to subtract from each other. My x-variable will represent the number of hot dogs and my y-variable will represent the number of sodas.

3x+2y=213

x  + y =87

We need to make sure one of the monomials are alike in each equation, so we can eliminate a variable. Distribute 3 to each number/variable in the second equation.

3x+2y=213

3(x+y=87) --> 3x+3y=261

Now we can eliminate x.

  3x+2y=213

-  3x+3y=261

----------------------

        -y=-48  

Divide -1 to both sides to get y=48. So, you sold 48 cans of soda. Now, we can find the number of hot dogs by substituting 48 into the second equation to get x+48=87. Subtract 48 to both sides to result with x=39. So, you sold 39 hot dogs.

Question If Jim has 60 spoons and Jim has a friend named Jim that has 157 and has another friend named Jim with 537 spoons and pooled all their spoons together and Jim 1 took the spoons to a blacksmith to make small spoons by breaking the spoons to thirds and 27 spoons broke, Jim 1 had the blacksmith make a normal spoon from the remains which makes 3 normal spoons how many spoons do all the Jims have together and how many spoons do each Jim have individvally? I just thought of this on the spot so i dont know the answer anywho I need an answer cause i wanted to ask this to my friends and say the answer to seem smart lol

Answers

Step-by-step explanation:

Jim 1= 60 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

after Jim 1 took the spoons to the blacksmith he broke 27 spoons which means

Jim 1= 60-27 which leaves him with 33 spoons.

and now

Jim 1= 33 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

3 normal spoons outta 33 spoons which means he used 11 spoons per each spoon

and now

Jim 1= 3 spoons

Jim 2= 157 spoons

Jim 3= 537 spoons

so finally, all the Jims have 697 spoons in total.

a bit tuff...lol

have a great day mr/mrs. Jim creator :)

Step-by-step explanation:

While back-to-school shopping, you find two pairs of jeans that cost $29 each, three shirts that cost $16 each, and a pair of shoes for $21. What is the total cost of these items, if the store is offering a 30% discount?

Answers

Answer:

$88.9

Step-by-step explanation:

First, you have to calculate the total cost of the items by adding up the results of multiplying the price of each item for its quantity:

Total cost=(29*2)+(16*3)+21

Total cost=58+48+21

Total cost=127

Now, you have to calculate 30% of that total and subtract that amount from the total cost:

127*30%=$38.1

127-38.1=$88.9

According to this, the answer is that the total cost of these items is $88.9 if the store is offering a 30% discount.

Haley sells apples from her apple orchard. Last week, she sold 516 apples. Of those apples, 107 or green apples and the rest were red apples. On Monday, Harry's sells 100 apples. Based on last week sales, white how many of the 100 apples she sells on Monday could be expecting to be green.

Answers

Answer: About 21 apples

Step-by-step explanation:

Number of apples sold last week = 516

Number of green apples = 107

Number of red apples = 516 - 107 = 409

Number of apples sold on Monday = 100

Number of apples expected to be green will be:

= 107/516 × 100

= 20.7

= 21 Approximately

Cathy is making bows from a ribbon that is 11 1/5 yards long. She needs to cut the ribbon into equal pieces that measure 2/5 yard to make each bow. How many bows can Cathy make? Sam solved the problem below but got it incorrect. Explain Sam's error.

Answers

Answer:

28 bows

Step-by-step explanation:

Each bow is an equal piece.

1 bow = 2/5 yard

Total yard of ribbon = 11 1/5 yards

Hence:

2/5 yard = 1 bow

11 1/5 yards = x

2/5x = 11 1/5

x = 11 1/5 ÷ 2/5

x = 56/5 ÷ 2/5

x = 56/5 × 5/2

x = 28 bows

Therefore, Cathy can make 28 bows

f(n) = 3(2)^n = 3 * 2^n.

We can see here that 3 is a constant term.

When n = 0, f(0) = 3 * 2^0 = 3.

Hence, on the 1st day 3 leaves fell. (A)

When n = 1, f(1) = 3 * 2^1 = 6.

When n = 2, f(2) = 3 * 2^2 = 12.

Notice that the number of leaves that fell keep doubling.

Therefore the number of leaves that fell on a given day is 2 times the number of leaves that fell on the previous day. (D)
