In 1990, a total of $514 billion was spent on food and drinks in a particular country. In 2003, the total spent was $904 billion.
(a)
Find the equation of the exponential function that can be used to model the total T spent (in billions of dollars) on food and drinks in this country as a function of the number of years t since 1990. (Round your decimal value to four decimal places.)
T = answer a
(b)
Use your model to predict the amount spent (in billions of dollars) in 2000. (Round your answer to the nearest integer.)
answer b billion dollars
(c)
What is your prediction for the total sales of food and drink (in billions of dollars) in 2018? (Round your answer to the nearest integer.)
answer c billion dollars
(d)
Estimate when the total sales will reach $2 trillion if this exponential trend continues. (Round your answer to two decimal places.)
t = answer d
