Since both Luke and Will spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 4 u - 1 u
= 3 u
3 u = 60
1 u = 60 ÷ 3 = 20
Amount that Luke had in the end
= 4 u
= 4 x 20
= $80
Amount that Luke had spent
= 115 - 80
= $35
Amount that each of them spent every day
= 35 ÷ 7
= $5
Answer(s): $5
