Jenson and Cole had the same number of stamps. Jenson gave away
57 of his stamps while Cole gave away
35 of his stamps. Given that Jenson gave away 12 stamps more than Cole, how many stamps did Jenson have at first?
| |
Jenson's stamps |
Cole's stamps |
| Before |
7x5 =
35 u |
5x7 =
35 u |
| Change |
- 5x5 =
- 25 u |
- 3x7 =
- 21 u |
| After |
2x5 =
10 u |
2x7 =
14 u |
The number of cards that Jenson and Cole each had at first is the same. Make the number of cards that Jenson and Cole each had at first the same. LCM of 7 and 5 is 35.
Number of stamps that Jenson gave away more than Cole
= 25 u - 21 u
= 4 u
4 u = 12
1 u = 12 ÷ 4 = 3
Number of stamps that Jenson had at first
= 35 u
= 35 x 3
= 105
Answer(s): 105
