A model for the average price of a pound of white sugar in a certain country from August 1993 to August 2003 is given by the function S(t) = −0.00003237t5 + 0.0009037t4 − 0.008956t3 + 0.03629t2 − 0.04457t + 0.3582 where t is measured in years since August of 1993. Estimate the times when sugar was cheapest and most expensive during the period 1993-2003. (Round your answers to three decimal places.) t= _________ (cheapest) t= _________ (most expensive)

Step 1
We are given a polynomial function \( S(t) \) that models the average price of a pound of white sugar over a period from August 1993 to August 2003. We need to find the times \( t \) when the sugar was cheapest and most expensive. The function is: \[ S(t) = Show more…

The cost of a can of Coca-Cola in 1960 was $0.10. The exponential function that models the cost of a Coca Cola by year is given below, where t is the number of years since 1960. C(t) = 0.10e^(0.0576t) Find the expected cost of a can of Coca-Cola in 2000, 2005, 2035, and 2040 (rounded to the nearest cent). They expected the cost of Coca-Cola to be $ in 2000, $ in 2005, $ in 2035, and $ in 2040.
