practice solving and using literal equations. tahmar knows the formula for simple interest is $i = prt$, where $i$ represents the simple interest on an amount of money, $p$, for $t$ years at $r$ rate. she transforms the equation to isolate $p$: $p=\frac{i}{rt}$. using this formula, what is the amount of money, $p$, that will generate $20 at a 5% interest rate over 5 years?
Answer
Explanation:
Step1: Identify values
$I = 20$, $r=0.05$, $t = 5$
Step2: Substitute values into formula
$P=\frac{I}{rt}=\frac{20}{0.05\times5}$
Step3: Calculate the value of P
$P=\frac{20}{0.25}=80$
Answer:
$80$
