If $60 is put in an account that gets 7% and I add $15 per year, how much will I have at the end of 8 years?

Respuesta :

It will be the one that equals 7/12

Answer with explanation:

Amount in my account =$ 60

→Amount in my account after 8 years, if rate of interest is 7%

Amount→(using the formula of compound interest)

 [tex]=P(1+\frac{R}{100})^t\\\\=60(1+\frac{7}{100})^8\\\\=60\times(1.07)^8\\\\=60\times 1.7181\\\\=103.10[/tex]  

→And $ 15 is added every year in my account for 8 years.

Total Money after 8 years  = $15×8=$120  

Total Money in my Account after 8 years = $103.10+$120

                                  =$223.10
