The population of a town at present is 80,000. If the annual rate of increase is 4%, find the population after 4 years. (Use the formula: $A = p{\left( {1 + \dfrac{r}{{100}}} \right)^n}$, where p is the original population).

Hint: To find the new population, we are going to use the formula given to us by putting the values in the formula. In this question, p is 80,000, r is 4% and n is 4 years.
Complete step-by-step answer: The population of the town at present is given to be equal to 80,000. The rate at which the population increases is given to be 4%. We are supposed to find the population of the town after 4 years, We have all the data required to find the new population, let us put the values in the formula, $A = p{\left( {1 + \dfrac{r}{{100}}} \right)^n}$ $A = 80000{\left( {1 + \dfrac{4}{{100}}} \right)^4}$ $A = 93588.685$ $A = 93589$
Note: Make sure to not mistake the values of old and new population while assigning it to the formula. In the formula, A is the new population, p is the old population, the value of r is 4% and n is 4 years.
