You invest $2,000 in an account that has an annual interest rate of 3.2%, compounded annually. how much money will be in the account after 12 years? round your answer to the nearest whole number.

P = 2000 is the amount invested
r = 0.032 is the decimal form of 3.2%, which is the interest rate
n = 1 indicates we compound 1 time a year (compound annually)
t = 12 is the number of years

Those four values are plugged into the formula below
A = P*(1+r/n)^(n*t)
A = 2000*(1+0.032/1)^(1*12)
A = 2918.6792
A = 2919

Rounded to the nearest whole dollar, you'll have about $2919 in the account

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
