1% = 165 ÷ 65
1% = $2.40
100% = 2.4 x 100
100% = $240
The original price 20 years ago was $240.
240 - 156 = $84
The current price is $84.
I will try my best!
Ok so, I'll try to make this explanation super simple for you.
The denominator will always go on the outside and the numerator will be on the inside. Let me give you an example.
Take x^2/3. The answer will be 3√(x^2). Do you see how the 3 is on the outside and the 2 is on the outside?
Take p^4/5. The answer will be 5√(p^4).
I hope this gives you a clear understanding.
