Julie sold $1800 worth of skirts and vests. She earned $600 less on the vests than the skirts. Each vest is sold for $6 more than each skirt. The number of vests sold was ²₅ of the number of skirts sold.

1. How much did Julie earn from the sales of the skirts?
2. How many vests were sold?

(a)
Amount that Julie earned from the sales of the skirts
= (1800 + 600) ÷ 2
= 2400 ÷ 2
= $1200 

(b)
Amount that Julie earned from the sales of the vests
= 1200 - 600
= $600

Number of sets of vests sold = 2  
Number of sets of skirts sold = 5

Cost of 1 set of vests sold
= 600 ÷ 2
= $300

Cost of 1 set of skirts sold
= 1200 ÷ 5
= $240

Amount that 1 set of vests was more than 1 set of skirts 
= 300 - 240
= $60

Number of items in 1 set
= 60 ÷ 6
= 10

Number of vests sold
= 2 x 10
= 20

Answer(s): (a) $1200 ; (b) 20
