Xandra sold $844 worth of windbreakers and shirts. She earned $108 less on the shirts than the windbreakers. Each shirt is sold for $6 more than each windbreaker. The number of shirts sold was ⁴₇ of the number of windbreakers sold.

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

(a)
Amount that Xandra earned from the sales of the windbreakers
= (844 + 108) ÷ 2
= 952 ÷ 2
= $476 

(b)
Amount that Xandra earned from the sales of the shirts
= 476 - 108
= $368

Number of sets of shirts sold = 4  
Number of sets of windbreakers sold = 7

Cost of 1 set of shirts sold
= 368 ÷ 4
= $92

Cost of 1 set of windbreakers sold
= 476 ÷ 7
= $68

Amount that 1 set of shirts was more than 1 set of windbreakers 
= 92 - 68
= $24

Number of items in 1 set
= 24 ÷ 6
= 4

Number of shirts sold
= 4 x 4
= 16

Answer(s): (a) $476 ; (b) 16
