Cost of each jumpsuit
=
25 x 90
= $36
Total amount collected from selling the vests and the jumpsuits on the first day
= 450 u + 36 u
= 486 u
486 u = 13608
1 u = 13608 ÷ 486 = 28
Number of jumpsuits sold on the first day
= 1 u
= 28
(b)
Total number of items left after the first day
= 12 u
= 12 x 28
= 336
Answer(s): (a) 28; (b) 336
