Marion took a taxi from her office to her home. Her taxi fare was based on the charges shown. The taxi stopped once at a traffic light for 3 minutes and travelled a total distance of 6.4 km to reach Marion's home. How much was her taxi fare?

Taxi Fare
First km	$3.60
Every additional 300 m or less	$0.25
Every 35 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.60

Remaining distance to pay for
= 6.4 - 1
= 5.4 km

1 km = 1000 m
5.4 km = 5.4 x 1000 = 5400 m

Sets of additional 300 m
= 5400 ÷ 300
= 18 r 0

Amount to pay for remaining 5.4 km
= 18 x 0.25
= $4.50

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 35 seconds of waiting
= 180 ÷ 35
= 5 r 5

Sets of 35 seconds of waiting or less
= 5 + 1
= 6

Amount to pay for sets of 35 seconds of waiting or less
= 6 x 0.40
= $2.40

Marion's taxi fare
= 3.60 + 4.50 + 2.40
= $10.50

Answer(s): $10.50
