Question

Brooke bought 5 plates for $44. If the price of the plates is always the same, which represents the total cost, y, of buying any number of plates, x?

Answer 1

y = 8.80x

Explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y = $8.80(10) = $88

If x = 100, y = $8.80(100) = $880

Answer 2

y = 8.80x

Explanation:

Th price of one plate = $44 / 5 = $8.80

the cost of any x plate can be determined by multiplying $8.80 by x

y = $8.80x

For example if x is 10, y = $8.80(10) = $88

If x = 100, y = $8.80(100) = $880
