	Hoodies	Shirts
Number of sets	3 sets	1 set
Compare each		$7 more
Total value	$585	$230

Total cost of shirts
= (815 - 355) ÷ 2
= $230

Total cost of hoodies
= 230 + 355
= $585

3 sets of hoodies = $585
1 set of hoodies = 585 ÷ 3 = $195 

1 set of shirts = $230

Difference in 1 set of shirts and 1 set of hoodies
= 230 - 195
= $35

Number of clothing in 1 set
= 35 ÷ 7
= 5

Cost of 1 hoodie
= 195 ÷ 5
= $39

Cost of 1 shirt
= 39 + 7
= $46

Price of 9 hoodies and 10 shirts
= (9 x 39) + (10 x 46)
= 351 + 460
= $811

Answer(s): $811
