Jaslyn sold $1211 worth of skirts and vests. She earned $77 less on the vests than the skirts. Each vest is sold for $4 more than each skirt. The number of vests sold was ³₄ of the number of skirts sold.

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

(a)
Amount that Jaslyn earned from the sales of the skirts
= (1211 + 77) ÷ 2
= 1288 ÷ 2
= $644 

(b)
Amount that Jaslyn earned from the sales of the vests
= 644 - 77
= $567

Number of sets of vests sold = 3  
Number of sets of skirts sold = 4

Cost of 1 set of vests sold
= 567 ÷ 3
= $189

Cost of 1 set of skirts sold
= 644 ÷ 4
= $161

Amount that 1 set of vests was more than 1 set of skirts 
= 189 - 161
= $28

Number of items in 1 set
= 28 ÷ 4
= 7

Number of skirts sold
= 4 x 7
= 28

Answer(s): (a) $644 ; (b) 28
