3 multiple choice 2 points solve the formula (simple interest) ( i = prt ) for the letter ( r ). ( r = ipt ) ( r = i + pt ) ( r = i - pt ) ( r = \frac{i}{pt} )
Answer
Explanation:
Step1: Isolate ( r )
Given ( I = Prt ), divide both sides by ( Pt ). $$\frac{I}{Pt}=\frac{Prt}{Pt}$$
Step2: Simplify
Cancel out ( Pt ) on the right - hand side. $$\frac{I}{Pt}=r$$
Answer:
( r=\frac{I}{Pt} ) (the fourth option)
