Cost of each coat
=
45 x 50
= $40
Total amount collected from selling the vests and the coats on the first day
= 250 u + 40 u
= 290 u
290 u = 5220
1 u = 5220 ÷ 290 = 18
Number of coats sold on the first day
= 1 u
= 18
(b)
Total number of items left after the first day
= 18 u
= 18 x 18
= 324
Answer(s): (a) 18; (b) 324
