1. ## BASIC STORY PROBLEM-urgent

The Parts Department Profit Is 12% On A New Magneto. How Much Does The Magneto Cost If The Selling Price Is $145.60. 2. 145.6 x .12=17.472 so take 145.6 - 17.472=$128.128 so the answer is $128.19 Or at least I'm pretty sure. 3. Basically, it's saying "112% of what is$145.60"? It's 112% since we're talking about profit - the selling price includes 12% profit and the 100% of the original cost.

Set up a proportion:

$\frac{112}{100} = \frac{145.50}{x}$.

I got $130 by cross-multiplying and solving. As a check, if the cost is$130 and they make 12%, the total selling price should be $130 + 12% of 130. 12% of 130 is$15.60.
