Ali had y stamps. His father gave him 20 more stamps. He then shared all his stamps equally with his 2 brothers.
a) How many stamps did each boy get in terms of y?
b) If y = 28, how many stamps did each boy get?
Solution
a)
Number of stamps Ali had at first ----- y
After father gave another 20 stamps ----- y + 20
After sharing with 2 other brothers ----- (y + 20) divided by 3
= (y + 20)/3 (Answer)
b) If y = 28 -----
(28 + 20)/3 stamps
= 48/3 stamps
= 16 stamps (Answer)
