Tina sold $2853 worth of jackets and vests. She earned $801 less on the vests than the jackets. Each vest is sold for $9 more than each jacket. The number of vests sold was ³₇ of the number of jackets sold.

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

(a)
Amount that Tina earned from the sales of the jackets
= (2853 + 801) ÷ 2
= 3654 ÷ 2
= $1827 

(b)
Amount that Tina earned from the sales of the vests
= 1827 - 801
= $1026

Number of sets of vests sold = 3  
Number of sets of jackets sold = 7

Cost of 1 set of vests sold
= 1026 ÷ 3
= $342

Cost of 1 set of jackets sold
= 1827 ÷ 7
= $261

Amount that 1 set of vests was more than 1 set of jackets 
= 342 - 261
= $81

Number of items in 1 set
= 81 ÷ 9
= 9

Number of vests sold
= 3 x 9
= 27

Answer(s): (a) $1827 ; (b) 27
