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.
The amount you would pay if you will use one of their computers for:
40 minutes is within the range of the first 2 hours. Therefore, you will pay P20.00 using their computers for 40 minutes.
3 hours can be divided into: 2 hours + 1 hour
Charges per hour for the first 2 hours = P20.00
Charges for each succeeding hour = Additional P10.00
Hence: 2 hours + 1 hour
P20.00 + P10.00
= P30.00
Therefore, you will pay P30.00 using their computers for 3 hours.
Converting 150 minutes to hours
60 minutes = 1 hour
150 minutes = ?
150/60
= 2 .5 hours = 2 hours 30 minutes
3 hours can be divided into: 2 hours + 1 hour
Charges per hour for the first 2 hours = P20.00
Charges for each succeeding hour = Additional P10.00
Therefore, you will pay
2 hours + 30 minutes
P20.00 + P10.00
= P30.00
Therefore, you will pay P30.00 using their computers for 150 minutes.
