Make a problem involving exponential growth
Explanation:
The expression given is similar to the formula for compound interest, so the word problem must involve something to do with exponential growth. This can be a population of animals, cells, birds etc.
The starting number is 500.
The rate of growth is
There are 20 intervals of time - whether this is days, weeks, months, years, will be your choice.
Note that it is an expression, not an equation, because it is not equal to a given value yet, and there is no unknown to solve for,
So you could start off with something like..
A population of 500 penguins increases at a rate of .....
How many will there be after .....
Hope this helps.
This is an equation of compounded growth. See explanation for one possible worded question.
Explanation:
What is the final sum in a savings account after 20 years if the principle sum is 500 and the compound interest is 1.75% calculated annually?
Note that
So the equation would look like this:
