2. A computer shop charges P20.00 per hour (or a fraction of an hour) for the first two hours and an additional P10.00 per hour for each succeeding hour. Find how
much you would pay if you will use one of their computers for: (a) 40 minutes (b) 3
hours (C) 150 minutes?

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.

(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.
