Ashirt is on sale for 30% off. the sale price is $51.50. what was the orginail price?

The answer is $329.00
To contract an original price from a sale price, use:
Original price- Original Price*Mark-down percent = Sale Price, or
Original price- Original price *(Mark-down precent) = sale price
To do a do a double mark-down problem, we must do this twice for the 10%:
Original Sale Price*(1-10%)= $207.27
Original Sale Price = $207.27/0.9 = 230.30.
For the pre-sale discount price.
Original Price *(1-30%)= $230.30
Original Price= 230.30/0.7 = $329.00

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
