Wendy 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 7.3 km to reach Wendy's home. How much was her taxi fare?

Taxi Fare
First km	$3.20
Every additional 500 m or less	$0.25
Every 40 seconds waiting or less	$0.40

Amount to pay for the first 1 km = $3.20

Remaining distance to pay for
= 7.3 - 1
= 6.3 km

1 km = 1000 m
6.3 km = 6.3 x 1000 = 6300 m

Sets of additional 500 m
= 6300 ÷ 500
= 12 r 300

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

Amount to pay for remaining 6.3 km
= 13 x 0.25
= $3.25

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 40 seconds of waiting
= 120 ÷ 40
= 3 r 0

Amount to pay for sets of 40 seconds of waiting or less
= 3 x 0.40
= $1.20

Wendy's taxi fare
= 3.20 + 3.25 + 1.20
= $7.65

Answer(s): $7.65
