is the amount of rooms painted, and 
For Pete's Painting Company, they charge a flat fee of $60, so we will have a constant of 60.
They also charge 20$ per room, meaning that we will multiply 20 by

Answer:
All of the above
Step-by-step explanation:
The question is asking you which equation you can use for you to find the value of the undefined variable, n.
In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.
Becca: in 1 hour;
(3(3/4) miles in 1/2 hour)2
=7.5 miles in 1 hour
Alice: in 1 hour;
(5(1/4) miles in 3/4 hours)
She travels 5(1/4)/3 = 1.75 miles in 1/4 hours.
Travels 1.75x4 = 7 miles in 1 hour
As seen, Becca runs faster, 0.5 miles per hour faster.
