Jen sold $1264 worth of sweaters and skirts. She earned $16 less on the skirts than the sweaters. Each skirt is sold for $10 more than each sweater. The number of skirts sold was ³₅ of the number of sweaters sold.

1. How much did Jen earn from the sales of the sweaters?
2. How many skirts were sold?

(a)
Amount that Jen earned from the sales of the sweaters
= (1264 + 16) ÷ 2
= 1280 ÷ 2
= $640 

(b)
Amount that Jen earned from the sales of the skirts
= 640 - 16
= $624

Number of sets of skirts sold = 3  
Number of sets of sweaters sold = 5

Cost of 1 set of skirts sold
= 624 ÷ 3
= $208

Cost of 1 set of sweaters sold
= 640 ÷ 5
= $128

Amount that 1 set of skirts was more than 1 set of sweaters 
= 208 - 128
= $80

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

Number of skirts sold
= 3 x 8
= 24

Answer(s): (a) $640 ; (b) 24
