Since both Lee and Jack spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 5 u - 1 u
= 4 u
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that Lee had in the end
= 5 u
= 5 x 20
= $100
Amount that Lee had spent
= 190 - 100
= $90
Amount that each of them spent every day
= 90 ÷ 10
= $9
Answer(s): $9
