Sample Problem

The table below shows the rates of charge for bus fare.

Payment per trip

$0.85

Monthly payment (unlimited trips)

$24

If Arthur on average makes 34 trips each month,

(a) Which method of payment should he choose to save money? (type “monthly” or “per trip”)

(b) How much money could he save? dollars cents

Solution

If Arthur chooses the payment per trip: 0.85 × 34 = 28.90.

28.90 > 24

(a) Monthly payment will be more economical.

(b) 28.90 – 24 = 4.90
