Fanny sold $2260 worth of vests and jackets. She earned $260 less on the jackets than the vests. Each jacket is sold for $7 more than each vest. The number of jackets sold was ⁴₇ of the number of vests sold.

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

(a)
Amount that Fanny earned from the sales of the vests
= (2260 + 260) ÷ 2
= 2520 ÷ 2
= $1260 

(b)
Amount that Fanny earned from the sales of the jackets
= 1260 - 260
= $1000

Number of sets of jackets sold = 4  
Number of sets of vests sold = 7

Cost of 1 set of jackets sold
= 1000 ÷ 4
= $250

Cost of 1 set of vests sold
= 1260 ÷ 7
= $180

Amount that 1 set of jackets was more than 1 set of vests 
= 250 - 180
= $70

Number of items in 1 set
= 70 ÷ 7
= 10

Number of vests sold
= 7 x 10
= 70

Answer(s): (a) $1260 ; (b) 70
