Since both Neave and Oliver 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 = 60
1 u = 60 ÷ 2 = 30
Amount that Neave had in the end
= 3 u
= 3 x 30
= $90
Amount that Neave had spent
= 110 - 90
= $20
Amount that each of them spent every day
= 20 ÷ 4
= $5
Answer(s): $5
