Cathy sold $468 worth of sweaters and dresses. She earned $12 less on the dresses than the sweaters. Each dress is sold for $7 more than each sweater. The number of dresses sold was ³₅ of the number of sweaters sold.

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

(a)
Amount that Cathy earned from the sales of the sweaters
= (468 + 12) ÷ 2
= 480 ÷ 2
= $240 

(b)
Amount that Cathy earned from the sales of the dresses
= 240 - 12
= $228

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

Cost of 1 set of dresses sold
= 228 ÷ 3
= $76

Cost of 1 set of sweaters sold
= 240 ÷ 5
= $48

Amount that 1 set of dresses was more than 1 set of sweaters 
= 76 - 48
= $28

Number of items in 1 set
= 28 ÷ 7
= 4

Number of dresses sold
= 3 x 4
= 12

Answer(s): (a) $240 ; (b) 12
