Raeann sold $2580 worth of windbreakers and jumpsuits. She earned $1060 less on the jumpsuits than the windbreakers. Each jumpsuit is sold for $12 more than each windbreaker. The number of jumpsuits sold was ²₇ of the number of windbreakers sold.

1. How much did Raeann earn from the sales of the windbreakers?
2. How many windbreakers were sold?

(a)
Amount that Raeann earned from the sales of the windbreakers
= (2580 + 1060) ÷ 2
= 3640 ÷ 2
= $1820 

(b)
Amount that Raeann earned from the sales of the jumpsuits
= 1820 - 1060
= $760

Number of sets of jumpsuits sold = 2  
Number of sets of windbreakers sold = 7

Cost of 1 set of jumpsuits sold
= 760 ÷ 2
= $380

Cost of 1 set of windbreakers sold
= 1820 ÷ 7
= $260

Amount that 1 set of jumpsuits was more than 1 set of windbreakers 
= 380 - 260
= $120

Number of items in 1 set
= 120 ÷ 12
= 10

Number of windbreakers sold
= 7 x 10
= 70

Answer(s): (a) $1820 ; (b) 70
