Answer:
P = Rs2500
Step-by-step explanation:
Given that,
Amount, A = Rs 3025
Rate, r = 10%
Let time, t = 2 years
We need to find the sum if the amount is compounded annually. Using the formula of compound interest.

So, the sum of money is Rs 2500.
Given that the production of n stalks of corn planted has been modeled by (2n^2-2n), then the approximate ears of corn produced by 3 stalks will be given by:
2n^2-2n
plugging in n=3 in the formula we get:
2(3)^2-2(3)
simplifying we get:
2(9)-6
=18-6
=12
the answer is: 12 ears
