Vanessa 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 4.6 km to reach Vanessa's home. How much was her taxi fare?

Taxi Fare
First km	$3.20
Every additional 300 m or less	$0.42
Every 35 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.20

Remaining distance to pay for
= 4.6 - 1
= 3.6 km

1 km = 1000 m
3.6 km = 3.6 x 1000 = 3600 m

Sets of additional 300 m
= 3600 ÷ 300
= 12 r 0

Amount to pay for remaining 3.6 km
= 12 x 0.42
= $5.04

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15

Sets of 35 seconds of waiting or less
= 3 + 1
= 4

Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.40
= $1.60

Vanessa's taxi fare
= 3.20 + 5.04 + 1.60
= $9.84

Answer(s): $9.84
