Answer
Estimate: 240; Exact: 233
Work Step by Step
The equation for calculating the total cost of the U-Haul is the fixed cost + cost per mile x number of miles.
To estimate, we round 55 to 60, and round 89 to 90, and use the rounded numbers in the equation to calculate the total cost:
60 + 2*90 = 240
To find the exact cost, we use the actual numbers in the equation:
55 + 2*89 = 233
