Doctors use intravenous (IV) drips to deliver fluids and medications to patients. Suppose an IV drip starts with 1,000 ml of saline and dispenses fluid at a rate of 2.5 ml per minute. a. Write an equation for this situation using F to represent the amount of fluid (saline solution) left in milliliters and t to represent the time in minutes. Hint: If you have trouble writing a model, try making a table first. F-1000-2.5t b. Is this a linear model? ? Explain your answer. c. How long will it take to use all of the saline solution? Give you answer in hours and minutes. 6 This is not a decimal or integer value. minutes hours and 40j d. Which of the following can be used to describe the point you found in Part (c)?
