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
