Gabby 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 8.6 km to reach Gabby's home. How much was her taxi fare?

Taxi Fare
First km	$3.30
Every additional 500 m or less	$0.41
Every 40 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $3.30

Remaining distance to pay for
= 8.6 - 1
= 7.6 km

1 km = 1000 m
7.6 km = 7.6 x 1000 = 7600 m

Sets of additional 500 m
= 7600 ÷ 500
= 15 r 100

Sets of additional 500 m or less
= 15 + 1
= 16

Amount to pay for remaining 7.6 km
= 16 x 0.41
= $6.56

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 0.20
= $0.60

Gabby's taxi fare
= 3.30 + 6.56 + 0.60
= $10.46

Answer(s): $10.46
