Fiona sold $1785 worth of shirts and dresses. She earned $35 less on the dresses than the shirts. Each dress is sold for $9 more than each shirt. The number of dresses sold was ⁵₇ of the number of shirts sold.

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

(a)
Amount that Fiona earned from the sales of the shirts
= (1785 + 35) ÷ 2
= 1820 ÷ 2
= $910 

(b)
Amount that Fiona earned from the sales of the dresses
= 910 - 35
= $875

Number of sets of dresses sold = 5  
Number of sets of shirts sold = 7

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

Cost of 1 set of shirts sold
= 910 ÷ 7
= $130

Amount that 1 set of dresses was more than 1 set of shirts 
= 175 - 130
= $45

Number of items in 1 set
= 45 ÷ 9
= 5

Number of dresses sold
= 5 x 5
= 25

Answer(s): (a) $910 ; (b) 25
