Cost of each coat
=
23 x 120
= $80
Total amount collected from selling the blazers and the coats on the first day
= 120 u + 80 u
= 200 u
200 u = 2800
1 u = 2800 ÷ 200 = 14
Number of coats sold on the first day
= 1 u
= 14
(b)
Total number of items left after the first day
= 6 u
= 6 x 14
= 84
Answer(s): (a) 14; (b) 84
