Zoe 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 5.7 km to reach Zoe's home. How much was her taxi fare?

Taxi Fare
First km	$3.40
Every additional 500 m or less	$0.23
Every 30 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.40

Remaining distance to pay for
= 5.7 - 1
= 4.7 km

1 km = 1000 m
4.7 km = 4.7 x 1000 = 4700 m

Sets of additional 500 m
= 4700 ÷ 500
= 9 r 200

Sets of additional 500 m or less
= 9 + 1
= 10

Amount to pay for remaining 4.7 km
= 10 x 0.23
= $2.30

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

Zoe's taxi fare
= 3.40 + 2.30 + 1.80
= $7.50

Answer(s): $7.50
