$0.09
$0.08

Answer 1

The answer is $0.09.

3.10/32=0.09

Answer 2

Answer: $0.10

Explanation:

Given : The current cost of gasoline is $3.10 per gallon.

Jeanie's car averages 32 miles per gallon.

i.e. The gallons of gasoline required for 32 miles = 1 gallon

Then , the gallons of gasoline required for 1 mile=
`(1)/(32)` gallons

Now, the cost for each mile will be :-

`(1)/(32)*3.10=0.096875\approx0.10\ \  \text{(To the nearest cent)}`

Hence, the cost per mile =$0.10
