A pillow that usually costs $18 is marked down 25%. Use the table to find the pillow’s new price.

Fill in the missing amounts to solve the problem.

100 percent is an 18 dollar original price, 25 percent markdown is a, and new price is b.

a =
b =

In this case we can propose a rule of three:

$ 18 > 100%

x > 25%

Where x represents the discount made to the pillow:

So we have the new price (with the discount) is:

In addition, if 25% is discounted we have to, the price of the pillow is 75% of the original price. That is to say:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
