Answer: C. $39.98
Step-by-step explanation:
We have the following equation with mixed fractions:
(1)
A mixed fraction is the combination of an integer and a fraction, and to convert it into an improper fraction and be able to solve the equation more easily, we must do the following:
Mixed fraction: 
Converting Mixed fraction to improper fraction: 
So, for both mixed fractions we have:
Having this clear, let's solve the equation:
(2)
(3)
Finally:
Don't make the mistake of saying that the new function is up above the given function. f(x) + 3 is not above f(x) = x. f(x) + 3 is below f(x).
The answer is B <<<<<=====
y + 3 = x is the way you can think of it.
y = x - 3 is what it is. If you have a graphing calculator, graph it. You want to see that it is below f(x) = x or going down.
First you need to get x on one side so subtract 3x from both sides which will leave you with 8=2x-20. Next add 20 to both sides to get 28=2x. Then divide everything by 2 and you should get x = 14.
