Martina drove 320 miles using 12 gallons of gas. At this rate, how many gallons of gas would she need to drive 296 miles?

Sure, here are the steps to solve the problem:

1. First, we need to find out how many miles Martina drives per gallon of gas. We do this by dividing the total miles she drove (320 miles) by the total gallons of gas she used (12 gallons).

   320 miles / 12 gallons = 26.67 miles/gallon

2. Next, we need to find out how many gallons of gas Martina would need to drive 296 miles. We do this by dividing the total miles she needs to drive (296 miles) by the number of miles she drives per gallon of gas (26.67 miles/gallon).

   296 miles / 26.67 miles/gallon = 11.1 gallons

So, Martina would need approximately 11.1 gallons of gas to drive 296 miles.
