Cost of each skirt
=
14 x 60
= $15
Total amount collected from selling the dresses and the skirts on the first day
= 240 u + 15 u
= 255 u
255 u = 7650
1 u = 7650 ÷ 255 = 30
Number of skirts sold on the first day
= 1 u
= 30
(b)
Total number of items left after the first day
= 25 u
= 25 x 30
= 750
Answer(s): (a) 30; (b) 750
