Cost of each windbreaker
=
12 x 40
= $20
Total amount collected from selling the skirts and the windbreakers on the first day
= 200 u + 20 u
= 220 u
220 u = 3300
1 u = 3300 ÷ 220 = 15
Number of windbreakers sold on the first day
= 1 u
= 15
(b)
Total number of items left after the first day
= 24 u
= 24 x 15
= 360
Answer(s): (a) 15; (b) 360
