Factoring an interest formula 
20200929 

From Kenneth: Hello
P + Pr has a common factor of P so it can be expressed as P(1 + r) after the P is factored out..
How does the "P" get in front of (1 + r)?
P/P + Pr/P = 1 + r What step is used to show that P is added in front of (1 + r)?
I thank you for your reply. Answered by Harley Weston.
