Step-by-step explanation:

Remark

If you find out the cost of 1 oz of each of them, that will determine the best buy. The smallest number is the best buy.

Givens

7 oz cost $2.38

15 oz cost $5.25

26 oz cost $8.58

Solution

<h3>7 oz</h3>

7 oz cost $2.38

1 oz cost  x                  This is a proportion. 3 quatities are known. Find x Cross multiply.

7/1 = 2.38/x

7x = 2.38

x = $0.34 dollars

<h3>15 oz</h3>

15 oz cost 5.25

1 oz costs x

15.1/1 = 5,25 x              Cross Multiply

15x = 5.25 * 1               Divide by 15                                

x = 5.25 / 15

x = $0.35

<h3>26 oz</h3>

26 oz cost 8.58

1 oz   cost x

26/1 = 8.38/x                 Cross Multiply

26x  = 8.38                    Divide by 26

x = 8.38/20

x = 0.32 dollars

Answer

7 oz cost  0.34

15 oz cost 0.35

26 oz cost 0.32

<h3>The best buy is 0.32 / oz for 26 oz</h3>

If y varies directly as x and k=8 , find x when y =8
Tju [1.3M]

Answer:

x = 1

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

here k = 8, thus

y = 8x ← equation of variation

When y = 8, then

8x = 8 ( divide both sides by 8 )

x = 1

Please show your work. Thank you for taking the time of day to help me!

Answer:

30

Step-by-step explanation:

Look at the bottom line of the chart.

He sold 41 sides of French fries and 40 sides of onion rings.

41 + 40 = 81

Since he sold a total of 81 sides with bacon cheeseburgers, that means he sold a total of 81 bacon cheeseburgers.

We have a ratio:

81 bacon cheeseburgers to 40 sides of onion rings

Now he sold 120 bacon cheeseburgers, so we set up a proportion to find the number of sides of onion rings. Let the unknown number be x.

81 burgers is to 40 sides as 120 burgers is to x sides

81/40 = 120/x

We solve for x by cross multiplying.

81x = 40 * 120

81x = 4800

x = 4800/81 = 59.3

That means he serves 59 sides of onion rings.

Each serving of onion rings is half pound.

59 * 0.5 = 29.5

For 120 bacon cheeseburgers, he serves approximately 29.5 lb of onion rings.
