Use the formula I = Prt to find the principal,P : 鈸� whenI = $2,160, r = 6%,t = 3 years 鈸� in general

Short Answer

Expert verified

$a.Thesimplifiedvalueisp=1200$

$b . Ingeneralp= \frac{I}{(rt)}$

Step by step solution

Step 1. Given information

The given equation is :I= Prt

We have toUse the formula I= Prtto find the principal,P : 鈸� whenI = $2,160, r= 6%,t= 3 years 鈸� in general

Step 2. Explanation

$\begin{array}{l} Solve:Writetheformula \\ 鈬� I = P r t \\ 鈬� 2160 = P (0.06) (3) (Substitute) \\ 鈬� 2160 = p (3) (Simplify) \\ 鈬� \frac{2160}{0.18} = \frac{P (0.18)}{0.18} (Dividebothsidestoisolatet) \\ 鈬� 12000 = p (Simplify) \\ Thesimplifiedvalueisp=1200 \end{array}$

Part b. Step 3. Explanation

$\begin{array}{l} Ingeneral \\ Writetheformula. \\ 鈬� I=Prt \\ 鈬� I=P(rt)(Simplify) \\ 鈬� \frac{I}{(rt)} = \frac{P(rt)}{(rt)} (Dividebothsidestoisolatep) \\ 鈬� \frac{I}{(rt)} =p(Simplify) \\ Ingeneralp= \frac{I}{(rt)} \end{array}$
