Cost of each coat
=
15 x 60
= $12
Total amount collected from selling the blouses and the coats on the first day
= 60 u + 12 u
= 72 u
72 u = 864
1 u = 864 ÷ 72 = 12
Number of coats sold on the first day
= 1 u
= 12
(b)
Total number of items left after the first day
= 6 u
= 6 x 12
= 72
Answer(s): (a) 12; (b) 72
