Answer:

22.88 mpg

Step-by-step explanation:

An increase of 4% can be represented as (100% + 4%). Think of it as you're getting 100% and an additional 4%.

Now multiple your original mileage by the increase:

22(100% + 4%)

=22(1.00 + .04)

=22(1.04)

=22.88

Maria Fay's mileage would be 22.88 mpg with the new tires.

How to find an increase in value using percentage?

When we say that a certain value increases by 6%, it means it is 6% better than before. If we assume 100% is the current value. Then (100+6)% would be the new value.

We can find Maria Fay's mileage as shown below:

Maria Fay's mileage is given as 22 miles per gallon.

It is given that the salesperson told Maria Fay that the mileage would increase by 4%.

4% of her mileage can be found below:

4% of 22 mpg = 4/100 * 22 mpg

= 0.88 mpg

Therefore, Maria Fay's total mileage is:

Her initial mileage + 4% increase in mileage = 22 + 0.88 mpg

= 22.88 mpg

Therefore, we have found that Maria Fay's mileage would be 22.88 mpg with the new tires.
