Since both Cole and Fred spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 2 u - 1 u
= 1 u
1 u = 25
1 u = 25 ÷ 1 = 25
Amount that Cole had in the end
= 2 u
= 2 x 25
= $50
Amount that Cole had spent
= 77 - 50
= $27
Amount that each of them spent every day
= 27 ÷ 3
= $9
Answer(s): $9
