Answer:
$ 71.5
Step-by-step explanation:
firstly kilometer to meters
<em>1 km = 1000 m </em>
therefore 3 km = 3000m
for the first 500 = $40
hence deduct the 500 from 3000m
3000 - 500 = 2500
now find out how many 300m go into 2500
2500 / 300 = 8.33
which is rounded up to 9
therefore the total amount is :
40 + 9 * 3.5
<u>= $71.5</u>
