Cost of each blouse
=
15 x 40
= $8
Total amount collected from selling the dresses and the blouses on the first day
= 160 u + 8 u
= 168 u
168 u = 2520
1 u = 2520 ÷ 168 = 15
Number of blouses sold on the first day
= 1 u
= 15
(b)
Total number of items left after the first day
= 15 u
= 15 x 15
= 225
Answer(s): (a) 15; (b) 225
