Answer:
7662207.35
Explanation:
We are asked to find the present value of a 20 years annuity at rate equal 10%
[tex]present \: value = annuity \times \frac{1 - {(1 + rate)}^{ - time} }{rate} [/tex]
[tex]900000 \times \frac{1 - {1.1}^{ - 20} }{.1} = 7662207.35[/tex]
Remember:
on present time: power is negative and the 1 comes first
[tex]1 - {(1 + rate)}^{ - time} [/tex]
on future value: the power is positive and comes first then you subtract 1
[tex] {(1 + rate)}^{time} - 1[/tex]
