Zoe sold $2961 worth of blouses and windbreakers. She earned $441 less on the windbreakers than the blouses. Each windbreaker is sold for $8 more than each blouse. The number of windbreakers sold was ⁴₇ of the number of blouses sold.

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

(a)
Amount that Zoe earned from the sales of the blouses
= (2961 + 441) ÷ 2
= 3402 ÷ 2
= $1701 

(b)
Amount that Zoe earned from the sales of the windbreakers
= 1701 - 441
= $1260

Number of sets of windbreakers sold = 4  
Number of sets of blouses sold = 7

Cost of 1 set of windbreakers sold
= 1260 ÷ 4
= $315

Cost of 1 set of blouses sold
= 1701 ÷ 7
= $243

Amount that 1 set of windbreakers was more than 1 set of blouses 
= 315 - 243
= $72

Number of items in 1 set
= 72 ÷ 8
= 9

Number of windbreakers sold
= 4 x 9
= 36

Answer(s): (a) $1701 ; (b) 36
