I have to say 11%

A = P(1 + r/n)nt
A = 1,500.00(1 + 0.11/4)(4)(1)
A = 1,500.00(1 + 0.0275)(4)
A = $1,671.93

Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $1,500.00 at a rate of 11% per year compounded 4 times per year over 1 years is $1,671.93.

Given:

You have $1,000 to invest in an account, and need to have $1,500 in one year.

Required:

What interest rate would you need to have in order to reach this goal if the amount is compounded quarterly?

Step-by-step explanation:

The formula we need is


\begin{gathered} r=n[((A)/(P))^{(1)/(nt)}-1] \\ Where, \\ n(compounded) \\ A(Total) \\ P(Principal) \\ t(time) \end{gathered}

Now,


\begin{gathered} r=n[((A)/(P))^{(1)/(nt)}-1] \\ r=4*[((1500)/(1000))^{(1)/(4*1)}-1] \\ r=0.426728 \\ \text{ Then, convert r to R as a percentage} \\ R=r*100 \\ R=0.426728*100 \\ R=42.673\% \end{gathered}
