How long will it take $5,000 to double in an account that pays 1.6% simple interest?

43.667 years

Step-by-step explanation:

Simple Interest Rate Formula: A = P(1 + r)ⁿ

Step 1: Define variables

A = 10,000

P = 5,000

r = 0.016

n = unknown

Step 2: Substitute variables

10,000 = 5,000(1 + 0.016)ⁿ

Step 3: Solve for n time

2 = (1.016)ⁿ

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.
