Cindy sold $1760 worth of blouses and windbreakers. She earned $368 less on the windbreakers than the blouses. Each windbreaker is sold for $10 more than each blouse. The number of windbreakers sold was ³₇ of the number of blouses sold.

1. How much did Cindy earn from the sales of the blouses?
2. How many blouses were sold?

(a)
Amount that Cindy earned from the sales of the blouses
= (1760 + 368) ÷ 2
= 2128 ÷ 2
= $1064 

(b)
Amount that Cindy earned from the sales of the windbreakers
= 1064 - 368
= $696

Number of sets of windbreakers sold = 3  
Number of sets of blouses sold = 7

Cost of 1 set of windbreakers sold
= 696 ÷ 3
= $232

Cost of 1 set of blouses sold
= 1064 ÷ 7
= $152

Amount that 1 set of windbreakers was more than 1 set of blouses 
= 232 - 152
= $80

Number of items in 1 set
= 80 ÷ 10
= 8

Number of blouses sold
= 7 x 8
= 56

Answer(s): (a) $1064 ; (b) 56
