Xuan sold $1179 worth of blouses and dresses. She earned $207 less on the dresses than the blouses. Each dress is sold for $7 more than each blouse. The number of dresses sold was ³₇ of the number of blouses sold.

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

(a)
Amount that Xuan earned from the sales of the blouses
= (1179 + 207) ÷ 2
= 1386 ÷ 2
= $693 

(b)
Amount that Xuan earned from the sales of the dresses
= 693 - 207
= $486

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

Cost of 1 set of dresses sold
= 486 ÷ 3
= $162

Cost of 1 set of blouses sold
= 693 ÷ 7
= $99

Amount that 1 set of dresses was more than 1 set of blouses 
= 162 - 99
= $63

Number of items in 1 set
= 63 ÷ 7
= 9

Number of blouses sold
= 7 x 9
= 63

Answer(s): (a) $693 ; (b) 63
