Question

Kimberly went shopping for holiday presents. She bought boxes of chocolates and boxes of ornaments for her coworkers. Boxes of chocolate cost $11 each and boxes of ornaments cost $10 each. She buys a total of 17 boxes and spends $179. How many boxes of chocolates and how many boxes of ornaments does she buy?

Answer 1

X+Y = 17

11x + 10y = 179

11x + 10(17-x) = 179

11x + 170 - 10x = 179

x + 170 = 179

x = 9

y=8
