Barbara 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 7.1 km to reach Barbara's home. How much was her taxi fare?

Taxi Fare
First km	$3.80
Every additional 500 m or less	$0.36
Every 45 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.80

Remaining distance to pay for
= 7.1 - 1
= 6.1 km

1 km = 1000 m
6.1 km = 6.1 x 1000 = 6100 m

Sets of additional 500 m
= 6100 ÷ 500
= 12 r 100

Sets of additional 500 m or less
= 12 + 1
= 13

Amount to pay for remaining 6.1 km
= 13 x 0.36
= $4.68

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 0.30
= $0.90

Barbara's taxi fare
= 3.80 + 4.68 + 0.90
= $9.38

Answer(s): $9.38
