truck drivers report the mileage or number of miles m traveled per gallon of gas g for each trip driver went the farthest on one gallon of gas

Answer 1

Answer: the answer is Andy

Explanation:

Answer 2

Andy went as furthest as possible with a gallon of gasoline

Explanation:

Let

m ----> the distance in miles

g ----> the number of gallons of gas

step 1

Kelley's Mileage

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

Andy's Mileage

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
