Luke had
14 as much money as Riordan at first. After Luke received $163 and Riordan received $70, both of them had the same amount of money. How much did Riordan have at first?

Luke |
Riordan |
Before |
1 u |
4 u |
Change |
+ 163 |
+ 70 |
After |
1 u + 163 |
4 u + 70 |
The amount that Luke and Riordan had in the end is the same.
1 u + 163 = 4 u + 70
4 u - 1 u = 163 - 70 = 93
3 u = 93
1 u = 93 ÷ 3 = 31
Amount that Riordan had at first
= 4 u
= 4 x 31
= $124
Answer(s): $124
