Question

Two stores sell the same refrigerator for the same original price. Store A advertises that the refrigerator is on sale for 15% off the original price. Store B advertises that it is reducing the refrigerator’s price by $150. When Stephanie compares the sale prices of the refrigerator in both stores, she concludes that the sale prices are equal.

Which equation models this situation?

Let p represent the refrigerator’s original price.

A.0.85p = p – 150
B.0.85(p – 150) = p
C.0.15p = p − 150
D.0.15p = p + 180

Answer 1

i really don't understand this stuff

Answer 2

I think the answer is C. I multiplied each of them out with p = 500, and none of them turned out to be correct, but they don't ask us to do that. So here's what we know:

Store A is discounting the Fridge by 15%.
Store B is subtracting $150 from the original price for the Fridge.
'p' is the original price.
So you now know that 15%, $150, and 'p' all HAVE to be in the equation.

A and B don't make any sense. A is multiplying p by 0.85 (which is 100-15), which isn't what we're supposed to do. B is saying that 0.85 multiplied by p - 150 is equal to p, which isn't correct.

D doesn't make any sense either. 180 isn't given to us in the instructions, 150 is.

C makes the most sense. It says that the original price of the fridge is multiplied by the 15% (on the left side) and on the other side(the right side) it says that the original price is reduced by 150. Making sense?

Answer 3

yes it does
