w = 2 x h
t = h - 4
3w + 2h + 5t = 136
20.
3(2h) + 2h + 5(h - 4) = 136
6h + 2h + 5h - 20 = 136
13h = 156
h = 12
Cost of sweatshirt = $24
Cost of t-shirt = $8
Cost of one pair of shorts = $12
Hope this helps!! :)
Answer:

w = 2h
t = h - 4
3w + 2h + 5t = 136
20)
w = $24
t = $8
h = $12
Step-by-step explanation:
w = 2h
t = h - 4
3w + 2h + 5t = 136
3(2h) + 2h + 5(h - 4) = 136
6h + 2h + 5h - 20 = 136
13h = 156
h = 12
t = 12 - 4 = 8
w = 2(12) = 24
w = 2t
t = w - 4
w = 2(w - 4)
w = 2w - 8
w = 8
2t = 8
t = 4
Verification:
3(8) + 5(4) = 54
