Answer: $1,018
Explanation:
Cities are 90 miles apart so a roundtrip is 180 miles which means that the operating cost per trip is:
= 1.30 * 180
= $234
Total cost per trip = Divers cost + operating cost
= 275 + 234
= $509
Four trips are made per week so total cost is:
= 509 * 4
= $2,036
If each sent its truck twice a week and hauled the other firm's cargo on the return trip then savings would be:
= Cost of 4 trips - cost of 2 trips
= 2,036 - (509 * 2)
= $1,018
