Here,
CONDITION FOR STUDENT A
Time - 5. 11
Pay- $63.75
Therefore, The amount of money raised for 1 hour = 63.75/5

Amount of money raised for 1 hour = 147/12 = $12.25
Amount of money raised for 20 hour = 12.25 × 20 = $245
CONDITION FOR STUDENT C
p = 12.5h
Putting the value of h as 20
Pay for 20 hour = 12.5 × 20 = $250
