Teagan Clay · Answer 1

132 = x sweatshirts, 22 = y baseball caps

total merchandise sold: 154

x + y = 15420 x + 10 y = 2,86020 (132) + 10 (22) = 2,8602,640 + 220 = 2,860

x + y = 154132 + 22 = 154

-2x - y = 286-2 (132) - 22 = - 286

-x = - 132-132 = - 132

132 + y = 154132 + 22 = 154

Tristian · Answer 2

132 sweatshirts, 22 baseball caps.

1) Set up system of equations like:

x+y=154

20x+10y=2860

2) Solve

x+y=154

-2x-y=-286

-x=-132

x=132

132+y=154

y=22

3) Substitute answers into variables and check.
