using the interest formula a = p(1 + rt), solve for the indicated variable. solve for r. r = (simplify your answer.)
Answer
Explanation:
Step1: Divide both sides by P
$\frac{A}{P}=1 + rt$
Step2: Subtract 1 from both sides
$\frac{A}{P}-1=rt$
Step3: Divide both sides by t
$r=\frac{\frac{A}{P}-1}{t}=\frac{A - P}{Pt}$
Answer:
$\frac{A - P}{Pt}$
