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 3 minutes and travelled a total distance of 9.3 km to reach Betty's home. How much was her taxi fare?

Taxi Fare
First km	$2.80
Every additional 300 m or less	$0.32
Every 30 seconds waiting or less	$0.30

Amount to pay for the first 1 km = $2.80

Remaining distance to pay for
= 9.3 - 1
= 8.3 km

1 km = 1000 m
8.3 km = 8.3 x 1000 = 8300 m

Sets of additional 300 m
= 8300 ÷ 300
= 27 r 200

Sets of additional 300 m or less
= 27 + 1
= 28

Amount to pay for remaining 8.3 km
= 28 x 0.32
= $8.96

1 min = 60 s
3 min = 3 x 60 = 180 s

Sets of 30 seconds of waiting
= 180 ÷ 30
= 6 r 0

Amount to pay for sets of 30 seconds of waiting or less
= 6 x 0.30
= $1.80

Betty's taxi fare
= 2.80 + 8.96 + 1.80
= $13.56

Answer(s): $13.56
