Question

last month jen drove her car 4,404.6 miles. that brought the car’s total mileage to 78,511.6 miles. what was the car’s total mileage before last month?

Explanation:

Step1: Define the problem

We know the total mileage after last month (\(T = 78511.6\) miles) and the miles driven last month (\(d = 4404.6\) miles). We need to find the total mileage before last month (\(B\)). The relationship is \(T=B + d\), so we solve for \(B\) as \(B=T - d\).

Step2: Substitute the values

Substitute \(T = 78511.6\) and \(d = 4404.6\) into the formula: \(B=78511.6 - 4404.6\).

Step3: Perform the subtraction

\(78511.6-4404.6 = 74107\).

Answer:

The car's total mileage before last month was \(74107\) miles.
