Total cost of skirts
= (1060 - 572) ÷ 2
= $244
Total cost of hoodies
= 244 + 572
= $816
4 sets of hoodies = $816
1 set of hoodies = 816 ÷ 4 = $204
1 set of skirts = $244
Difference in 1 set of skirts and 1 set of hoodies
= 244 - 204
= $40
Number of clothing in 1 set
= 40 ÷ 10
= 4
Cost of 1 hoodie
= 204 ÷ 4
= $51
Cost of 1 skirt
= 51 + 10
= $61
Price of 3 hoodies and 7 skirts
= (3 x 51) + (7 x 61)
= 153 + 427
= $580
