postnew [5]

The interest rate will be equal to 24% in 2 years.

<h3>What is compound interest?</h3>

Given that:-

  • Find the interest rate if ​$32 increased to ​$50 in 2 years.

The interest rate will be calculated by using the following formula:-

A = P[1+\dfrac{r}{n}]^{nt}

50=32[1+\dfrac{r}{1}]^{2}

\dfrac{50}{32}=(1+r)^2

1.56 = ( 1 + r )²

√1.56 = ( 1 + r )

r = 1.24 - 1

r = 0.24

r = 24%

Therefore  interest rate will be equal to 24% in 2 years.
