Cost of each shirt
=
34 x 120
= $90
Total amount collected from selling the sweaters and the shirts on the first day
= 360 u + 90 u
= 450 u
450 u = 11250
1 u = 11250 ÷ 450 = 25
Number of shirts sold on the first day
= 1 u
= 25
(b)
Total number of items left after the first day
= 20 u
= 20 x 25
= 500
Answer(s): (a) 25; (b) 500
