Natalie sold $1818 worth of jumpsuits and coats. She earned $576 less on the coats than the jumpsuits. Each coat is sold for $4 more than each jumpsuit. The number of coats sold was ³₇ of the number of jumpsuits sold.

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

(a)
Amount that Natalie earned from the sales of the jumpsuits
= (1818 + 576) ÷ 2
= 2394 ÷ 2
= $1197 

(b)
Amount that Natalie earned from the sales of the coats
= 1197 - 576
= $621

Number of sets of coats sold = 3  
Number of sets of jumpsuits sold = 7

Cost of 1 set of coats sold
= 621 ÷ 3
= $207

Cost of 1 set of jumpsuits sold
= 1197 ÷ 7
= $171

Amount that 1 set of coats was more than 1 set of jumpsuits 
= 207 - 171
= $36

Number of items in 1 set
= 36 ÷ 4
= 9

Number of coats sold
= 3 x 9
= 27

Answer(s): (a) $1197 ; (b) 27
