Wesley bought 34 more stamps than Charlie and Charlie bought 13 stamps more than Gabby. The total number of stamps Wesley and Charlie bought was 5 times the number of stamps Gabby bought.
- How many stamps does Wesley need to give Charlie so that they have the same number of stamps?
- How many stamps did all three of them have altogether?
Wesley |
Charlie |
Gabby |
1 u + 13 + 34 |
1 u + 13 |
1 u |
5 u |
1 u |
(a)
Number of stamps that Wesley needs to give Charlie so that they have same number of stamps
= 34 ÷ 2
= 17
(b)
Total number of stamps that Wesley and Charlie had
= 1 u + 13 + 34 + 1 u + 13
= 1 u + 1 u + 13 + 34 + 13
= 2 u + 60
5 u = 2 u + 60
5 u - 2 u = 60
3 u = 60
1 u = 60 ÷ 3 = 20
Total number of stamps that all three of them had
= 5 u + 1 u
= 6 u
= 6 x 20
= 120
Answer(s): (a) 17; (b) 120
