Kylie 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 2 minutes and travelled a total distance of 9.7 km to reach Kylie's home. How much was her taxi fare?

Taxi Fare
First km	$3.80
Every additional 400 m or less	$0.36
Every 30 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.80

Remaining distance to pay for
= 9.7 - 1
= 8.7 km

1 km = 1000 m
8.7 km = 8.7 x 1000 = 8700 m

Sets of additional 400 m
= 8700 ÷ 400
= 21 r 300

Sets of additional 400 m or less
= 21 + 1
= 22

Amount to pay for remaining 8.7 km
= 22 x 0.36
= $7.92

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.40
= $1.60

Kylie's taxi fare
= 3.80 + 7.92 + 1.60
= $13.32

Answer(s): $13.32
