Reggie, Japheth and Dylan shared $246. During a shopping trip, Reggie spent
27 of his share, Japheth spent
34 of his share and Dylan spent
12 of his share. Given that all three boys each spent the same amount of money, how much more money do Reggie and Japheth have than Dylan at first?

Reggie |
Japheth |
Dylan |
Total |
Before |
7x3 = 21 u |
4x2 = 8 u |
2x6 = 12 u |
$246 |
Change |
- 2x3 = - 6 u |
- 3x2 = - 6 u |
- 1x6 = - 6 u |
|
After |
5x3 = 15 u |
1x2 = 2 u |
1x6 = 6 u |
|
The amounts that Reggie, Japheth and Dylan spent is the same. Make the amounts that each boy spent the same. LCM of 2, 3 and 1 is 6.
Amounts that the 3 boys had at first
= 21 u + 8 u + 12 u
= 41 u
41 u = 246
1 u = 246 ÷ 41 = 6
Amount that Reggie and Japheth have at first
= 21 u + 8 u
= 29 u
Amount that Reggie and Japheth have more than Dylan at first
= 29 u - 12 u
= 17 u
= 17 x 6
= $102
Answer(s): $102
