500=400(1+r)
We move all terms to the left:
500-(400(1+r))=0
We add all the numbers together, and all the variables
-(400(r+1))+500=0
We calculate terms in parentheses: -(400(r+1)), so:We get rid of parentheses
400(r+1)
We multiply parentheses
400r+400
Back to the equation:
-(400r+400)
-400r-400+500=0
We add all the numbers together, and all the variables
-400r+100=0
We move all terms containing r to the left, all other terms to the right
-400r=-100
r=-100/-400
r=1/4
