Pamela 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 9.2 km to reach Pamela's home. How much was her taxi fare?

Taxi Fare
First km	$3.90
Every additional 400 m or less	$0.25
Every 45 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.90

Remaining distance to pay for
= 9.2 - 1
= 8.2 km

1 km = 1000 m
8.2 km = 8.2 x 1000 = 8200 m

Sets of additional 400 m
= 8200 ÷ 400
= 20 r 200

Sets of additional 400 m or less
= 20 + 1
= 21

Amount to pay for remaining 8.2 km
= 21 x 0.25
= $5.25

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 0.20
= $0.60

Pamela's taxi fare
= 3.90 + 5.25 + 0.60
= $9.75

Answer(s): $9.75
