Nick spent $1122 on blouses and skirts. The number of skirts he bought was ¹₂ the number of blouses he bought. The cost of a skirt was $7 more than the cost of a blouse. He paid $318 more on blouses than on skirts. Find the cost of 4 blouses and 7 skirts.

	Blouses	Skirts
Number of sets	2 sets	1 set
Compare each		$7 more
Total value	$720	$402

Total cost of skirts
= (1122 - 318) ÷ 2
= $402

Total cost of blouses
= 402 + 318
= $720

2 sets of blouses = $720
1 set of blouses = 720 ÷ 2 = $360 

1 set of skirts = $402

Difference in 1 set of skirts and 1 set of blouses
= 402 - 360
= $42

Number of clothing in 1 set
= 42 ÷ 7
= 6

Cost of 1 blouse
= 360 ÷ 6
= $60

Cost of 1 skirt
= 60 + 7
= $67

Price of 4 blouses and 7 skirts
= (4 x 60) + (7 x 67)
= 240 + 469
= $709

Answer(s): $709
