Tiffany sold $1652 worth of coats and sweaters. She earned $98 less on the sweaters than the coats. Each sweater is sold for $12 more than each coat. The number of sweaters sold was ³₅ of the number of coats sold.

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

(a)
Amount that Tiffany earned from the sales of the coats
= (1652 + 98) ÷ 2
= 1750 ÷ 2
= $875 

(b)
Amount that Tiffany earned from the sales of the sweaters
= 875 - 98
= $777

Number of sets of sweaters sold = 3  
Number of sets of coats sold = 5

Cost of 1 set of sweaters sold
= 777 ÷ 3
= $259

Cost of 1 set of coats sold
= 875 ÷ 5
= $175

Amount that 1 set of sweaters was more than 1 set of coats 
= 259 - 175
= $84

Number of items in 1 set
= 84 ÷ 12
= 7

Number of coats sold
= 5 x 7
= 35

Answer(s): (a) $875 ; (b) 35
