First, since we're told there is a 29% discount on the original price, then $213 must be 71% of the original price because 100%-29%=71%. Then, it is also important to realize that we should use the decimal form of 71% which is 0.71. This is found by dividing 71 by 100 or simply moving the decimal point twice to the right. Then, we can write the equation 0.71x=213 where x represents the original price. This equation is essentially saying that 71% of some price is equal to $213. To solve this equation, you have to divide both sides by 0.71 to get x=$300 which is the final answer.
I hope this helps.
