a. Assuming that the advertised mileage estimates were correct, how many gallons of gasoline were used in the city? b. Assuming that the advertised mileage estimates were correct, how many gallons of gasoline were used on the highway?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
A salesperson purchased an automobile that was advertised as averaging 27miles per gallon of gasoline in the city and 38 miles per gallon on the highway. A recent sales trip that covered 2358 miles required 69 gallons of gasoline.
This problem does NOT ask for a distance, rate, or time, so do NOT use the formula d=r∙ t.
