7 0

Answer:

No.

Step-by-step explanation:

Change it so that both fractions would have the same denominator. Note that what you do to the denominator, you must also do to the numerator.

Multiply 3 to both the numerator & denominator of 8/20

(8/20)(3/3) = 24/60

24/60 ≠ 25/60 ∴ these 2 fractions are not proportional.

Can someone help me figure out the answer?
Ahat [919]

Answer:

You will break even on the car wash when you buy 13.5 gallons. As long as you buy that or more, it is cheaper to get the car wash.

Step-by-step explanation:

In order to find this, we need to create equations for both situations. If we let x equal the amount of gallons purchased, we can model the first equation as:

f(x) = 3.35x

And the second equation as:

f(x) = 3.05x + 4.05

Then to find when they equal each other, we can set the two equations equal to each other and solve for x.

3.35x = 3.05x + 4.05

0.30x = 4.05

x = 13.5

This means once you buy 13.5 gallons, the prices will be the same. Any amount over that and the car wash will be cheaper
