Answer: The correct option is (A)
Step-by-step explanation: Given that Frazier is saving money for college and has $1200 in savings. He earns $9 per hour. He saves 25% of his net pay after 20% taken out for tax.
We are to identify the expression that represents Frazier's savings.
Let, x represents the number of hours for which Frazier works.
So, the net pay of Frazier = $ 9x.
Since 20% of the net pay is taken out for tax, so total pay of Frazier after taking out tax is given by
Now, Frazier's savings from his net pay is given by
Since Frazier has $1200 already in savings, so the equation representing Frazier's savings will be
Thus, the required equation is
Option (A) is CORRECT.

Hello!
This is a problem about the general solution of a differential equation.
What we can first do here is separate the variables so that we have the same variable for each side (ex. with the
term and
with the
term).
Then, we can integrate using the power rule to get rid of the differentiating terms, remember to add the constant of integration, C, to at least one side of the resulting equation.
Then here, we just solve for and we have our general solution.
We can see that answer choice D has an equivalent equation, so answer choice D is the correct answer.
Hope this helps!
