Lucy 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 4.9 km to reach Lucy's home. How much was her taxi fare?

Taxi Fare
First km	$3.60
Every additional 300 m or less	$0.23
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.60

Remaining distance to pay for
= 4.9 - 1
= 3.9 km

1 km = 1000 m
3.9 km = 3.9 x 1000 = 3900 m

Sets of additional 300 m
= 3900 ÷ 300
= 13 r 0

Amount to pay for remaining 3.9 km
= 13 x 0.23
= $2.99

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 0.20
= $0.80

Lucy's taxi fare
= 3.60 + 2.99 + 0.80
= $7.39

Answer(s): $7.39
