celo used the simple interest formula $a = p(1 + rt)$ to calculate the interest he earned on his savings last month. which equation is equivalent to the simple interest formula?\n$p=\frac{a}{1 + rt}$\n$p=\frac{1+rt}{a}$\n$p = a-(1 + rt)$\n$p = a+(1 + rt)$
Answer
Explanation:
Step1: Isolate P
Given $A = P(1 + rt)$, divide both sides by $(1+rt)$ to solve for $P$. $P=\frac{A}{1 + rt}$
Answer:
$P=\frac{A}{1 + rt}$ (the first option)
