Xuan sold $1992 worth of sweaters and blouses. She earned $808 less on the blouses than the sweaters. Each blouse is sold for $12 more than each sweater. The number of blouses sold was ²₇ of the number of sweaters sold.

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

(a)
Amount that Xuan earned from the sales of the sweaters
= (1992 + 808) ÷ 2
= 2800 ÷ 2
= $1400 

(b)
Amount that Xuan earned from the sales of the blouses
= 1400 - 808
= $592

Number of sets of blouses sold = 2  
Number of sets of sweaters sold = 7

Cost of 1 set of blouses sold
= 592 ÷ 2
= $296

Cost of 1 set of sweaters sold
= 1400 ÷ 7
= $200

Amount that 1 set of blouses was more than 1 set of sweaters 
= 296 - 200
= $96

Number of items in 1 set
= 96 ÷ 12
= 8

Number of blouses sold
= 2 x 8
= 16

Answer(s): (a) $1400 ; (b) 16
