Answer:
(a) For 40 minutes the charge is P20.00
(b) For 3 hours the charge is P30.00
(c) For 150 minutes the charge is P30.00
Step-by-step explanation:
The given parameters are;
The amount the computer shop charges for the first two hours = P20.00
The amount the computer shop charges for a fraction of an hour = P20.00
The amount the computer shop charges for each extra hour = P10.00
Therefore, the amount the computer shop will charge for each time, is given as follows;
(a) For 40 minutes, we have;
The duration of 40 minutes is less than two hours, therefore, the amount the computer shop will charge = P20.00
(b) For a duration of 3 hours, the amount the computer shop will charge is given by the following relation
The amount charged for the first two hours = P20.00
The amount charged for the next extra hour to make 3 hours = P10.00
The total amount charged for the 3 hours = P20.00 + P10.00 = P30.00
(c) For a duration of 150 minutes, we have;
150 minutes = 2 hours 30 minutes
Therefore, the amount charged will be equivalent to the amount charged for 3 hours or P20.00 + P10.00 = P30.00.
