Cost of each skirt
=
45 x 70
= $56
Total amount collected from selling the dresses and the skirts on the first day
= 210 u + 56 u
= 266 u
266 u = 2394
1 u = 2394 ÷ 266 = 9
Number of skirts sold on the first day
= 1 u
= 9
(b)
Total number of items left after the first day
= 4 u
= 4 x 9
= 36
Answer(s): (a) 9; (b) 36
