Hazel sold $790 worth of blazers and coats. She earned $330 less on the coats than the blazers. Each coat is sold for $7 more than each blazer. The number of coats sold was ²₇ of the number of blazers sold.

1. How much did Hazel earn from the sales of the blazers?
2. How many blazers were sold?

(a)
Amount that Hazel earned from the sales of the blazers
= (790 + 330) ÷ 2
= 1120 ÷ 2
= $560 

(b)
Amount that Hazel earned from the sales of the coats
= 560 - 330
= $230

Number of sets of coats sold = 2  
Number of sets of blazers sold = 7

Cost of 1 set of coats sold
= 230 ÷ 2
= $115

Cost of 1 set of blazers sold
= 560 ÷ 7
= $80

Amount that 1 set of coats was more than 1 set of blazers 
= 115 - 80
= $35

Number of items in 1 set
= 35 ÷ 7
= 5

Number of blazers sold
= 7 x 5
= 35

Answer(s): (a) $560 ; (b) 35
