Nick spent $2030 on sweaters and shirts. The number of shirts he bought was ¹₄ the number of sweaters he bought. The cost of a shirt was $8 more than the cost of a sweater. He paid $1090 more on sweaters than on shirts. Find the cost of 9 sweaters and 7 shirts.

	Sweaters	Shirts
Number of sets	4 sets	1 set
Compare each		$8 more
Total value	$1560	$470

Total cost of shirts
= (2030 - 1090) ÷ 2
= $470

Total cost of sweaters
= 470 + 1090
= $1560

4 sets of sweaters = $1560
1 set of sweaters = 1560 ÷ 4 = $390 

1 set of shirts = $470

Difference in 1 set of shirts and 1 set of sweaters
= 470 - 390
= $80

Number of clothing in 1 set
= 80 ÷ 8
= 10

Cost of 1 sweater
= 390 ÷ 10
= $39

Cost of 1 shirt
= 39 + 8
= $47

Price of 9 sweaters and 7 shirts
= (9 x 39) + (7 x 47)
= 351 + 329
= $680

Answer(s): $680
