Final answer:
Mark's car gets 14 miles per gallon.
Step-by-step explanation:
To find the miles per gallon, we need to divide the number of miles driven by the number of gallons used. In this case, Mark drove 476 miles and used 34 gallons of gas. So, the miles per gallon can be calculated as:
Miles per gallon = Miles driven / Gallons of gas used
Plugging in the values:
Miles per gallon = 476 miles / 34 gallons = 14 miles per gallon
Therefore, Mark's car gets 14 miles per gallon.
