Eva sold $1416 worth of skirts and shirts. She earned $168 less on the shirts than the skirts. Each shirt is sold for $4 more than each skirt. The number of shirts sold was ²₃ of the number of skirts sold.

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

(a)
Amount that Eva earned from the sales of the skirts
= (1416 + 168) ÷ 2
= 1584 ÷ 2
= $792 

(b)
Amount that Eva earned from the sales of the shirts
= 792 - 168
= $624

Number of sets of shirts sold = 2  
Number of sets of skirts sold = 3

Cost of 1 set of shirts sold
= 624 ÷ 2
= $312

Cost of 1 set of skirts sold
= 792 ÷ 3
= $264

Amount that 1 set of shirts was more than 1 set of skirts 
= 312 - 264
= $48

Number of items in 1 set
= 48 ÷ 4
= 12

Number of skirts sold
= 3 x 12
= 36

Answer(s): (a) $792 ; (b) 36
