I am having a bit of trouble with the following equation:

(100p-4000/100p)=.3

Honestly, I don't know where to start with this one and would really appreciate some guidance on what steps to take.

Does the equation look like:

\(\displaystyle \displaystyle{\dfrac{100p-4000}{100p}}\)

Or:

\(\displaystyle \displaystyle{\dfrac{100p-4000}{100}p}\)

or:

\(\displaystyle \displaystyle{100p-\dfrac{4000}{100}p}\)

or something else...

Has your class not yet covered solving this sort of equation, so you haven't seen "multiplying both sides by the common denominator to clear the fractions"...? ;)

Top one.

Sorry, I don't know how to do equation formatting on the site yet.

You should have written it as:

(100*p - 4000)/(100*p) = 0.3

There are multiple ways to proceed from here. My preferred next step would be - to multiply both sides by (100p) - to get rid of fraction:

(100*p - 4000)/(100*p) = 0.3

(100*p - 4000)/(100*p) * 100*p = 0.3* 100*p

100*p -4000 = 30 * p

Now continue....
