Emily 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 4.1 km to reach Emily's home. How much was her taxi fare?

Taxi Fare
First km	$3.60
Every additional 300 m or less	$0.21
Every 45 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.60

Remaining distance to pay for
= 4.1 - 1
= 3.1 km

1 km = 1000 m
3.1 km = 3.1 x 1000 = 3100 m

Sets of additional 300 m
= 3100 ÷ 300
= 10 r 100

Sets of additional 300 m or less
= 10 + 1
= 11

Amount to pay for remaining 3.1 km
= 11 x 0.21
= $2.31

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

Emily's taxi fare
= 3.60 + 2.31 + 1.20
= $7.11

Answer(s): $7.11
