Opal sold $1376 worth of blazers and jumpsuits. She earned $136 less on the jumpsuits than the blazers. Each jumpsuit is sold for $4 more than each blazer. The number of jumpsuits sold was ⁵₇ of the number of blazers sold.

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

(a)
Amount that Opal earned from the sales of the blazers
= (1376 + 136) ÷ 2
= 1512 ÷ 2
= $756 

(b)
Amount that Opal earned from the sales of the jumpsuits
= 756 - 136
= $620

Number of sets of jumpsuits sold = 5  
Number of sets of blazers sold = 7

Cost of 1 set of jumpsuits sold
= 620 ÷ 5
= $124

Cost of 1 set of blazers sold
= 756 ÷ 7
= $108

Amount that 1 set of jumpsuits was more than 1 set of blazers 
= 124 - 108
= $16

Number of items in 1 set
= 16 ÷ 4
= 4

Number of blazers sold
= 7 x 4
= 28

Answer(s): (a) $756 ; (b) 28
