Henry bought 72 more stamps than Nick and Nick bought 21 stamps more than Kimberly. The total number of stamps Henry and Nick bought was 5 times the number of stamps Kimberly bought.
- How many stamps does Henry need to give Nick so that they have the same number of stamps?
- How many stamps did all three of them have altogether?
Henry |
Nick |
Kimberly |
1 u + 21 + 72 |
1 u + 21 |
1 u |
5 u |
1 u |
(a)
Number of stamps that Henry needs to give Nick so that they have same number of stamps
= 72 ÷ 2
= 36
(b)
Total number of stamps that Henry and Nick had
= 1 u + 21 + 72 + 1 u + 21
= 1 u + 1 u + 21 + 72 + 21
= 2 u + 114
5 u = 2 u + 114
5 u - 2 u = 114
3 u = 114
1 u = 114 ÷ 3 = 38
Total number of stamps that all three of them had
= 5 u + 1 u
= 6 u
= 6 x 38
= 228
Answer(s): (a) 36; (b) 228
