Taxi Fare |
|
First km |
$3.70 |
Every additional 400 m or less |
$0.39 |
Every 35 seconds waiting or less |
$0.20 |
Amount to pay for the first 1 km = $3.70
Remaining distance to pay for
= 9.5 - 1
= 8.5 km
1 km = 1000 m
8.5 km = 8.5 x 1000 = 8500 m
Sets of additional 400 m
= 8500 ÷ 400
= 21 r 100
Sets of additional 400 m or less
= 21 + 1
= 22
Amount to pay for remaining 8.5 km
= 22 x 0.39
= $8.58
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
Tammy's taxi fare
= 3.70 + 8.58 + 0.80
= $13.08
Answer(s): $13.08
