Rachel 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 7.5 km to reach Rachel's home. How much was her taxi fare?

Taxi Fare
First km	$2.80
Every additional 500 m or less	$0.42
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.80

Remaining distance to pay for
= 7.5 - 1
= 6.5 km

1 km = 1000 m
6.5 km = 6.5 x 1000 = 6500 m

Sets of additional 500 m
= 6500 ÷ 500
= 13 r 0

Amount to pay for remaining 6.5 km
= 13 x 0.42
= $5.46

1 min = 60 s
2 min = 2 x 60 = 120 s

Sets of 35 seconds of waiting
= 120 ÷ 35
= 3 r 15

Sets of 35 seconds of waiting or less
= 3 + 1
= 4

Amount to pay for sets of 35 seconds of waiting or less
= 4 x 0.20
= $0.80

Rachel's taxi fare
= 2.80 + 5.46 + 0.80
= $9.06

Answer(s): $9.06
