Cost of each blazer
=
25 x 90
= $36
Total amount collected from selling the coats and the blazers on the first day
= 90 u + 36 u
= 126 u
126 u = 2394
1 u = 2394 ÷ 126 = 19
Number of blazers sold on the first day
= 1 u
= 19
(b)
Total number of items left after the first day
= 2 u
= 2 x 19
= 38
Answer(s): (a) 19; (b) 38
