Wendy sold $564 worth of coats and jumpsuits. She earned $156 less on the jumpsuits than the coats. Each jumpsuit is sold for $5 more than each coat. The number of jumpsuits sold was ²₅ of the number of coats sold.

1. How much did Wendy earn from the sales of the coats?
2. How many coats were sold?

(a)
Amount that Wendy earned from the sales of the coats
= (564 + 156) ÷ 2
= 720 ÷ 2
= $360 

(b)
Amount that Wendy earned from the sales of the jumpsuits
= 360 - 156
= $204

Number of sets of jumpsuits sold = 2  
Number of sets of coats sold = 5

Cost of 1 set of jumpsuits sold
= 204 ÷ 2
= $102

Cost of 1 set of coats sold
= 360 ÷ 5
= $72

Amount that 1 set of jumpsuits was more than 1 set of coats 
= 102 - 72
= $30

Number of items in 1 set
= 30 ÷ 5
= 6

Number of coats sold
= 5 x 6
= 30

Answer(s): (a) $360 ; (b) 30
