Yen sold $392 worth of shirts and blazers. She earned $88 less on the blazers than the shirts. Each blazer is sold for $7 more than each shirt. The number of blazers sold was ²₅ of the number of shirts sold.

1. How much did Yen earn from the sales of the shirts?
2. How many shirts were sold?

(a)
Amount that Yen earned from the sales of the shirts
= (392 + 88) ÷ 2
= 480 ÷ 2
= $240 

(b)
Amount that Yen earned from the sales of the blazers
= 240 - 88
= $152

Number of sets of blazers sold = 2  
Number of sets of shirts sold = 5

Cost of 1 set of blazers sold
= 152 ÷ 2
= $76

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

Amount that 1 set of blazers was more than 1 set of shirts 
= 76 - 48
= $28

Number of items in 1 set
= 28 ÷ 7
= 4

Number of shirts sold
= 5 x 4
= 20

Answer(s): (a) $240 ; (b) 20
