Xylia 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 3 minutes and travelled a total distance of 7.5 km to reach Xylia's home. How much was her taxi fare?

Taxi Fare
First km	$3.70
Every additional 400 m or less	$0.32
Every 45 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $3.70

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 400 m
= 6500 ÷ 400
= 16 r 100

Sets of additional 400 m or less
= 16 + 1
= 17

Amount to pay for remaining 6.5 km
= 17 x 0.32
= $5.44

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 45 seconds of waiting
= 180 ÷ 45
= 4 r 0

Amount to pay for sets of 45 seconds of waiting or less
= 4 x 0.30
= $1.20

Xylia's taxi fare
= 3.70 + 5.44 + 1.20
= $10.34

Answer(s): $10.34
