You need to find a formula for the number of cars produced by a new plant that was opened 25twenty five days ago. You are told that 16sixteen days ago the plant had 215two hundred fifteen cars on hand, and that yesterday it had 440four hundred forty cars on hand. Assume that the plant produces cars at this same rate and has produced them at this same rate since it opened. Define a unit for the time elapsed from today. Enter a variable for the time elapsed from today and use this variable to write an expression for the total number of cars. How many cars will be on hand in fifteen days from now? When will the plant have 830eight hundred thirty cars on hand?
