The cost is $395.  You are trying to find <em>n</em> in 24<em>n</em> + 35.

Set C = 395.

You get 395 = 24<em>n</em> + 35.

Solve for <em>n</em> by first subtracting 35 from both sides of the equation:

395 - 35 = 360.

24<em>n</em> + 35 - 35 = 24<em>n</em>.

Now you have 360 = 24<em>n</em>.  Divide both sides by 24 to get:

15 = <em>n</em>.

So, 15 birthday cakes are made when the cost is $395.
