The equation is
(P×11.5%)+P=T
How do I isolate the variable P?
(P×11.5%)+P=T
How do I isolate the variable P?
You might start by factoring out P on the left-hand side.The equation is
(P×11.5%)+P=T
How do I isolate the variable P?
Really \(n\%=n\cdot 10^{-2}\) In this case because \(11.5=115\cdot 10^{-1}\) we get \(11.5\%=115\cdot 10^{-3}=0.115\)Taking the n% is the same as multiplying by n/100, use this to turn the equation into a linear equation
Good hint. 11.5% of P is the same as P×11.5/100Taking the n% is the same as multiplying by n/100, use this to turn the equation into a linear equation
Hi Goncarfabian. We've simplified the equation for you, using the decimal form of 11.5%How do I isolate the variable P?
