Total cost of skirts
= (1384 - 728) ÷ 2
= $328
Total cost of sweaters
= 328 + 728
= $1056
4 sets of sweaters = $1056
1 set of sweaters = 1056 ÷ 4 = $264
1 set of skirts = $328
Difference in 1 set of skirts and 1 set of sweaters
= 328 - 264
= $64
Number of clothing in 1 set
= 64 ÷ 8
= 8
Cost of 1 sweater
= 264 ÷ 8
= $33
Cost of 1 skirt
= 33 + 8
= $41
Price of 5 sweaters and 8 skirts
= (5 x 33) + (8 x 41)
= 165 + 328
= $493
Answer(s): $493
