Jen 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 7.9 km to reach Jen's home. How much was her taxi fare?

Taxi Fare
First km	$3.10
Every additional 300 m or less	$0.39
Every 45 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.10

Remaining distance to pay for
= 7.9 - 1
= 6.9 km

1 km = 1000 m
6.9 km = 6.9 x 1000 = 6900 m

Sets of additional 300 m
= 6900 ÷ 300
= 23 r 0

Amount to pay for remaining 6.9 km
= 23 x 0.39
= $8.97

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 45 seconds of waiting
= 120 ÷ 45
= 2 r 30

Sets of 45 seconds of waiting or less
= 2 + 1
= 3

Amount to pay for sets of 45 seconds of waiting or less
= 3 x 0.40
= $1.20

Jen's taxi fare
= 3.10 + 8.97 + 1.20
= $13.27

Answer(s): $13.27
