Mariah is putting $5,270 into an account earning 3.75% interest compounded quarterly. She estimates that it will take just over
galina1969 [7]

Answer:

a. Mariah’s estimate of the time is too low

Step-by-step explanation:

To answer this question, we are going to need to input the values in the question into the compound interest formula:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 3.75% into a decimal:

3.75% -> \frac{3.75}{100} -> 0.0375

Since the interest is compounded quarterly, we will use 4 for n. Lets plug in the values now:

A=5,270(1+\frac{0.0375}{4})^{4(9)}

A=7,373.98

Mariah's estimate of the time is too low. Your answer is A.
