3 u |
2 u |
Since both Liam and Simon spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 3 u - 1 u
= 2 u
2 u = 62
1 u = 62 ÷ 2 = 31
Amount that Liam had in the end
= 3 u
= 3 x 31
= $93
Amount that Liam had spent
= 129 - 93
= $36
Amount that each of them spent every day
= 36 ÷ 6
= $6
Answer(s): $6
