Bobby bought 78 more stamps than Caden and Caden bought 27 stamps more than Eva. The total number of stamps Bobby and Caden bought was 5 times the number of stamps Eva bought.
- How many stamps does Bobby need to give Caden so that they have the same number of stamps?
- How many stamps did all three of them have altogether?
Bobby |
Caden |
Eva |
1 u + 27 + 78 |
1 u + 27 |
1 u |
5 u |
1 u |
(a)
Number of stamps that Bobby needs to give Caden so that they have same number of stamps
= 78 ÷ 2
= 39
(b)
Total number of stamps that Bobby and Caden had
= 1 u + 27 + 78 + 1 u + 27
= 1 u + 1 u + 27 + 78 + 27
= 2 u + 132
5 u = 2 u + 132
5 u - 2 u = 132
3 u = 132
1 u = 132 ÷ 3 = 44
Total number of stamps that all three of them had
= 5 u + 1 u
= 6 u
= 6 x 44
= 264
Answer(s): (a) 39; (b) 264
