Cost of each dress
=
23 x 90
= $60
Total amount collected from selling the blazers and the dresses on the first day
= 90 u + 60 u
= 150 u
150 u = 900
1 u = 900 ÷ 150 = 6
Number of dresses sold on the first day
= 1 u
= 6
(b)
Total number of items left after the first day
= 8 u
= 8 x 6
= 48
Answer(s): (a) 6; (b) 48
