Betty 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 Betty's home. How much was her taxi fare?

Taxi Fare
First km	$3.30
Every additional 500 m or less	$0.39
Every 30 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.30

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 500 m
= 8200 ÷ 500
= 16 r 200

Sets of additional 500 m or less
= 16 + 1
= 17

Amount to pay for remaining 8.2 km
= 17 x 0.39
= $6.63

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 30 seconds of waiting
= 120 ÷ 30
= 4 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 4 x 0.40
= $1.60

Betty's taxi fare
= 3.30 + 6.63 + 1.60
= $11.53

Answer(s): $11.53
