felicia invested money at an interest rate of 4%. after six months, she had earned $90.00 interest. how much money did felicia invest?\n$i = prt$\n$90 = p(0.04)(0.5)$\n$90 = p(0.02)$\n$p=square$ dollars

Answer

Explanation:

Step1: Isolate the principal $p$.

Given $90 = p(0.02)$, we use the division - property of equality. Divide both sides of the equation by $0.02$. $p=\frac{90}{0.02}$

Step2: Calculate the value of $p$.

$\frac{90}{0.02}=\frac{90\times100}{0.02\times100}=\frac{9000}{2}=4500$

Answer:

$4500$
