You invest $9000 in an account that is compounded monthly at an interest rate of 7.5% for 3 years. a) (2pt) How much will be in the account after 3 years?

b) (1pt) How much interest will be earned?

a) $11,263.02

b) $2,263.02

Step-by-step explanation:

36 months in 3 years

monthly interest is 0.075/12 = 0.00625

V = 9000(1 + 0.00625)³⁶ = 11,263.01521... ≈ $11,263.02

$11,263.02 - 9000 = $2,263.02

$12. that is my answer.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
