Final answer:
The average miles per gallon for the SUV is 15 mpg, which is calculated by subtracting the difference of 29 mpg from the small car's average of 44 mpg.
Step-by-step explanation:
The student has asked to calculate the average miles per gallon (mpg) for an SUV if a small car averages 44 mpg and the small car gets 29 more mpg than the SUV. To find the mpg for the SUV, subtract 29 from the small car's mpg:
44 mpg (small car) - 29 mpg (difference) = 15 mpg (SUV).
Therefore, the SUV averages 15 miles per gallon.
