Nick spent $1660 on blouses and shirts. The number of shirts he bought was ¹₃ the number of blouses he bought. The cost of a shirt was $6 more than the cost of a blouse. He paid $740 more on blouses than on shirts. Find the cost of 4 blouses and 7 shirts.

	Blouses	Shirts
Number of sets	3 sets	1 set
Compare each		$6 more
Total value	$1200	$460

Total cost of shirts
= (1660 - 740) ÷ 2
= $460

Total cost of blouses
= 460 + 740
= $1200

3 sets of blouses = $1200
1 set of blouses = 1200 ÷ 3 = $400 

1 set of shirts = $460

Difference in 1 set of shirts and 1 set of blouses
= 460 - 400
= $60

Number of clothing in 1 set
= 60 ÷ 6
= 10

Cost of 1 blouse
= 400 ÷ 10
= $40

Cost of 1 shirt
= 40 + 6
= $46

Price of 4 blouses and 7 shirts
= (4 x 40) + (7 x 46)
= 160 + 322
= $482

Answer(s): $482
