Question

use the spreadsheet to answer the following question
if your car has an mpg of 34 and gas costs $4.25 a gallon, how many miles can you drive in a year if you want to keep your annual gas cost to no more than $1400?
...
you can drive no more than \boxed{} miles in a year to keep your annual gas cost to no more than $1400

Explanation:

Step1: Find gallons allowed

Let $g$ be gallons. Cost per gallon is $4.25$, total cost ≤ $1400$. So $4.25g \leq 1400$. Solve for $g$: $g \leq \frac{1400}{4.25} \approx 329.41$.

Step2: Find miles from gallons

Miles per gallon (mpg) is 34. Miles = mpg × gallons. So miles ≤ $34 \times 329.41 \approx 11199.94$.

Answer:

Approximately 11200 miles (or more precisely, $\frac{1400\times34}{4.25} = 11200$ miles).
