Erika 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 7.4 km to reach Erika's home. How much was her taxi fare?

Taxi Fare
First km	$2.30
Every additional 400 m or less	$0.31
Every 35 seconds waiting or less	$0.20

Amount to pay for the first 1 km = $2.30

Remaining distance to pay for
= 7.4 - 1
= 6.4 km

1 km = 1000 m
6.4 km = 6.4 x 1000 = 6400 m

Sets of additional 400 m
= 6400 ÷ 400
= 16 r 0

Amount to pay for remaining 6.4 km
= 16 x 0.31
= $4.96

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

Erika's taxi fare
= 2.30 + 4.96 + 0.80
= $8.06

Answer(s): $8.06
