Answer:

The mileage must the new model get so that the manufacturer meets the government requirement is 59 mpg.

Step-by-step explanation:

Consider the provided information.

Here it is given that the average mpg for the four models manufactured is 24 mpg.

The total mpg for the four models = 4 × 24 = 96

The manufacturer will add a model and the government standard is 31 mpg.

This can be written as:

[tex]\frac{96+x}{5}=31[/tex]

[tex]96+x=155[/tex]

[tex]x=155-96[/tex]

[tex]x=59[/tex]

Hence, the mileage must the new model get so that the manufacturer meets the government requirement is 59 mpg.
