The data given with regards to the population of US in 1998 written in mathematical form:
Population:
Annual consumption of ice cream:
Rate of annual consumption of ice cream:
Rate of population growth in the US in 1998:
Since we are told that:
annual per capita growth = (annual consumption) / (population size)
We can use calculus, specifically the quotient rule to determine the annual per capita consumption of ice cream increasing at that time.
The formula is as follows:
The annual per capita consumption of ice cream increased at that time in 1998 was 0.788
