Marty paid $72 for a jacket that had been marked down 20%. Create a linear model to represent this and use it to calculate the original price of the jacket.
Marty paid $60 for a jacket that had been marked down 20%. What is the original price of the jacket?
I really need this answer
To create a linear model, we can use the formula:
Original Price = Marked Down Price / (1 - Discount Percentage)
In this case, the marked down price of the jacket is $72 and the discount percentage is 20%.
Substituting these values into the formula, we can calculate the original price:
Original Price = $72 / (1 - 0.20)
Original Price = $72 / 0.80
Original Price = $90
Therefore, the original price of the jacket was $90.
(1 - .20)x = 72
so now find x
