Your friend borrows $100 from you and promises to pay you back $109 in 8 months. What annual percentage rate (A.P.R.) are you ch
NNADVOKAT [17]

Answer:

12.0\%=0.12

Step-by-step explanation:

We have been given that your friend borrows $100 from you and promises to pay you back $109 in 8 months.

We will use simple interest formula to solve our given problem.

A=P(1+rt), where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Convert 8 months to year:

\frac{8}{12}\text{ year}=\frac{2}{3}\text{ year}

108=100(1+r*\frac{2}{3})

108=100+r*\frac{2}{3}\times 100

108-100+r*\frac{200}{3}

108-100=100-100+r*\frac{200}{3}

8=r*\frac{200}{3}

8\times \frac{3}{200}=r*\frac{200}{3}\times \frac{3}{200}

\frac{24}{200}=r

r=\frac{24}{200}

r=0.12

Convert to percent:

0.12\times 100\%=12\%

Therefore, you are charging 12% APR to you friend.
