Document Summary
Word problems provide a main function that represent some type of a rate, and then ask to evaluate the total amount over the time interval. Same method of substitution applies as to theoretical questions. The key is to keep track of the units (often they are in hundreds, thousands, etc. ) and make sure to answer according to the context after the theoretical evaluation is done. A small town rising in popularity for tourism has its population growing at the rate shown by the function. This is a very easy function which does not require substitution. From now until three years later means the time interval is [ ] for the variable . Converting the interval to fit the substitution: when , Evaluating the total population over the interval [ ]: Therefore, the total population of the town after three years is: approximately people.
