Use the original price and the markdown to find the retail price. Original price: $70; Markdown: 24%

$53.20

Step-by-step explanation:

First, you need to find 24% of $70.

Change the percent to a decimal.

24% to .24.

Multiply that times 70.

.24 x 70 = 16.8

This will be the amount of money taken off the original price, so you will subtract it from the $70.

70 - 16.8 = 53.2

Therefore, the retail price is $53.20

i am sure it will be 90 degrees.

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
