Kathy 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 9.3 km to reach Kathy's home. How much was her taxi fare?

Taxi Fare
First km	$3.10
Every additional 500 m or less	$0.41
Every 30 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.10

Remaining distance to pay for
= 9.3 - 1
= 8.3 km

1 km = 1000 m
8.3 km = 8.3 x 1000 = 8300 m

Sets of additional 500 m
= 8300 ÷ 500
= 16 r 300

Sets of additional 500 m or less
= 16 + 1
= 17

Amount to pay for remaining 8.3 km
= 17 x 0.41
= $6.97

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 30 seconds of waiting
= 180 ÷ 30
= 6 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 6 x 0.40
= $2.40

Kathy's taxi fare
= 3.10 + 6.97 + 2.40
= $12.47

Answer(s): $12.47
