Jeanie's car averages 32 miles per gallon and the current cost of gasoline is $3.10 per gallon. to the nearest cent, what is the cost per mile?

$0.11
$0.10
$0.09
$0.08

$0.10

Step-by-step 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= gallons

Now, the cost for each mile will be :-

Hence, the cost per mile =$0.10

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

just sum

10 + 10 = 20
