Question

Suppose you have a savings account that has an APR of 7% and compounds daily. You want to have $4 trillion in your account in 25 years. How much would you need to deposit each month?

Answer 1

4000000000000 = p(1 + 0.07/365)^(25)(365)

4 x 10¹² = p(1.000191781)⁹¹²⁵

4 x 10¹² = 5.75363711p

0.695212423 x 10¹² = p

6.95212423 x 10¹¹
