RP
This is an example you could use to find out the solution to my problem!What we are trying to find is the regular price of the skateboard I bought. The question type is RP(Ratios and Proportions). We will use the systems RAIN, and MATH.
No problem! just always remember tp use RAISE and MATH systems to break down your problem to make it easier!
Wow so the original price was 45 dollars! That's an incredible discount! But thank you for explaining it to me!

So we have to create a MATH table, and input the given amounts. $18 dollars converted into a percent connecting with the given total(100) is 40%. The original in percentile is 100, but we have to find the original in dollars. So we will use cross multiplication.

So we multiply 18 by 100 as they are across each other on the table. And then we multiply 40 by x which is unknown. 18 multiplied by 100 is 18,000 and 40 by x is 40x. We then divide by 40 to isolate the variable and we get x = 45. Which indicates that 45 was the original price!
