Answer:
$19
Step-by-step explanation:
the following equations can be determined from the question
5j + 2s = 208 equation 1
3j + 4s = 178 equation 2
where j = jeans
s = sweatshirts
simultaneous equation would be used to determine the values
Multiply equation 1 by 2
10j + 4s = 416 equation 3
subtract equation 2 from 3
7j = 238
j= $34
substitute for j in equation 1
5(34) + 2s = 208
2s = 38
s = $19
