Answer: <u>Madison can travel 2.2 miles less than Anthony on one gallon of gas.</u>
Step-by-step explanation:
The equation y = 39.1 represents the number of miles,
, that madison can drive her car for every x gallons of gas.
Question: Madison can travel _ miles _ than Anthony on one gallon of gas.
Lets find how much Madison travels on 1 gallon of gas.
39.1(1) = 39.1
Therefore, Madison travels 39.1 miles on one gallon of gas.
Now lets solve for Anthony
Anthony travels 380.7 miles on 9 gallons of gas.
Therefore we can set up the equation:
9x = 380.7 to show that 9 gallons equates to 380.7 miles
to solve divide 9 from both sides
x = 41.3
So, Anthony travels 41.3 miles on one gallon of gas
Now find whether Madison travels more or less than Anthony on one gallon.
39.1 - 41.3 = -2.2
This means that Anthony can travel 2.2 miles more than Madison.
For your answer, this means that:
<u>Madison can travel 2.2 miles less than Anthony on one gallon of gas</u>
