How much interest is earned after 9 months if the original principal is $2500 and the rate is 3%?

Answer 1

Interest = #$56.25#

First we need to use the correct equation:

#I = p*r*t#
Where #I# is the amount of interest we earn, #p# is the Principal investment, #r# is the rate, and #t# is how much time in years.

Then we supply the given information into our equation.

#I = $2500 * 3% * 9/12#
Note: #3% = 0.03# & the time is #9/12# instead of #9# because #t# is in years

Finally we multiply to get our answer:

#2500 * 0.03 * 0.75 = 56.25#
So #$56.25# is how much interest was earned in 9 months at a #3%# interest rate.
Note: If the question asked how much money was left after 9 months #$56.25# would be incorrect for you would need to add the original investment aswell.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
