Answer:
15x + 25 = y
Step-by-step explanation:
$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y
Answer:

Step-by-step explanation:
Solve for the value of
:

-Take
and add it to
:


-Add both sides by
:


-Divide both sides by
:


Thus, the value of
is
.
We just need to solve the equation in order to find the value.

So we subtract 5 from both sides of the euqation and get

Now we divide by 3 on both sides and get

So the answer is C.
Hope this helps!
