Lynn sold $1595 worth of skirts and coats. She earned $155 less on the coats than the skirts. Each coat is sold for $11 more than each skirt. The number of coats sold was ⁴₇ of the number of skirts sold.

1. How much did Lynn earn from the sales of the skirts?
2. How many skirts were sold?

(a)
Amount that Lynn earned from the sales of the skirts
= (1595 + 155) ÷ 2
= 1750 ÷ 2
= $875 

(b)
Amount that Lynn earned from the sales of the coats
= 875 - 155
= $720

Number of sets of coats sold = 4  
Number of sets of skirts sold = 7

Cost of 1 set of coats sold
= 720 ÷ 4
= $180

Cost of 1 set of skirts sold
= 875 ÷ 7
= $125

Amount that 1 set of coats was more than 1 set of skirts 
= 180 - 125
= $55

Number of items in 1 set
= 55 ÷ 11
= 5

Number of skirts sold
= 7 x 5
= 35

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