Question

Matt and Ming are selling fruit for a school fundraiser. Customers can buy small boxes and large boxes of apples. Matt sold 5 small boxes of apples and 15 large boxes of apples for a total of $ 165 . Ming sold 11 small boxes of apples and 9 large boxes of apples for a total of $ 147 . Choose the system of equations that represent the situation.

Answer 1

$7; Cost of a box of apples (x)

$13; Cost of a box of oranges (y)

Explanation:

Matt: 3x + 14y = 203 3(-y + 20) + 14y = 203 3x + 14(13) = 203

Ming: 11x + 11y = 220 -3y + 60 + 14y = 203 3x + 182 = 203

11x = -11 11y = 143 3x = 21

x = -y + 20 y = 13 x = 7
