Lynn 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 9.6 km to reach Lynn's home. How much was her taxi fare?

Taxi Fare
First km	$3.20
Every additional 400 m or less	$0.39
Every 30 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.20

Remaining distance to pay for
= 9.6 - 1
= 8.6 km

1 km = 1000 m
8.6 km = 8.6 x 1000 = 8600 m

Sets of additional 400 m
= 8600 ÷ 400
= 21 r 200

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

Amount to pay for remaining 8.6 km
= 22 x 0.39
= $8.58

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 0.30
= $1.80

Lynn's taxi fare
= 3.20 + 8.58 + 1.80
= $13.58

Answer(s): $13.58
