Jade sold $1872 worth of jumpsuits and dresses. She earned $816 less on the dresses than the jumpsuits. Each dress is sold for $6 more than each jumpsuit. The number of dresses sold was ²₇ of the number of jumpsuits sold.

1. How much did Jade earn from the sales of the jumpsuits?
2. How many dresses were sold?

(a)
Amount that Jade earned from the sales of the jumpsuits
= (1872 + 816) ÷ 2
= 2688 ÷ 2
= $1344 

(b)
Amount that Jade earned from the sales of the dresses
= 1344 - 816
= $528

Number of sets of dresses sold = 2  
Number of sets of jumpsuits sold = 7

Cost of 1 set of dresses sold
= 528 ÷ 2
= $264

Cost of 1 set of jumpsuits sold
= 1344 ÷ 7
= $192

Amount that 1 set of dresses was more than 1 set of jumpsuits 
= 264 - 192
= $72

Number of items in 1 set
= 72 ÷ 6
= 12

Number of dresses sold
= 2 x 12
= 24

Answer(s): (a) $1344 ; (b) 24
