A car manufacturer produces three models of trucks and the average gas mileage of the three models must be at least 25 mpg. If the first two models get 20 mpg and 21 mpg, what must
the third model get? Create an inequality to represent the three models of trucks and the
average mpg. Solve the inequality and explain each of your steps. Graph your solutions on a
number line. Explain what your solution means.
