Cathy sold $600 worth of dresses and jumpsuits. She earned $24 less on the jumpsuits than the dresses. Each jumpsuit is sold for $5 more than each dress. The number of jumpsuits sold was ²₃ of the number of dresses sold.

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

(a)
Amount that Cathy earned from the sales of the dresses
= (600 + 24) ÷ 2
= 624 ÷ 2
= $312 

(b)
Amount that Cathy earned from the sales of the jumpsuits
= 312 - 24
= $288

Number of sets of jumpsuits sold = 2  
Number of sets of dresses sold = 3

Cost of 1 set of jumpsuits sold
= 288 ÷ 2
= $144

Cost of 1 set of dresses sold
= 312 ÷ 3
= $104

Amount that 1 set of jumpsuits was more than 1 set of dresses 
= 144 - 104
= $40

Number of items in 1 set
= 40 ÷ 5
= 8

Number of dresses sold
= 3 x 8
= 24

Answer(s): (a) $312 ; (b) 24
