Answer:
Andy went as furthest as possible with a gallon of gasoline
Step-by-step explanation:
Let
m ----> the distance in miles
g ----> the number of gallons of gas
step 1
<u><em>Kelley's Mileage</em></u>
Find the slope of the linear function of Kelley's Mileage
we have the points
(0,0) and (20,50)
the linear equation is
step 2
<u><em>Andy's Mileage</em></u>
Find the slope of the linear function of Andy's Mileage
we have the points
(15,78.75) and (30,157.5)
the linear equation is
step 3
Rick's Mileage
we have
therefore
the slope is
step 4
Compare the slopes
therefore
Andy went as furthest as possible with a gallon of gasoline
