Question

byron purchased a computer monitor at a 10% discount sale for 121.50. what was the original price of the monitor

Answer 1

So basically we do this: we know that if it's a 10% discount, it mean's it's 90% of the original price right?

Then let Original Price = P and N = New Price so we know:

P*0.9 = N So, we know that P = N/0.9, so you know N, just plug in and get P.

Answer 2

i dont know..

Answer 3

What do you mean you don't Know? I said it. Do N (Your after sale price) Divided by your discount rate (90% or 0.9)

So you do this:

\[121.5 \div 0.9 = Orignal Price\] And you get before discount price.
