After a discount of 20%, the sale price of a ride pass at a fun park is $40. What is the original price?

80$

Step-by-step explanation:

First set up an equation like this, where x is the original price:

x * 0.80 = 40

Because we know that 80 percent of the mystery number is 40, this works.

Then divide both sides by the 0.80 (remember it is 0.80 and not 80, because it is a percent value) to get:

x = 50

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
