7. Suppose that another drug is administered intravenously to an adult patient in a hospital as prescribed by a doctor. The relationship between the concentration of the drug (in mg/L) in the bloodstream and the time (in hours after administration) is modeled by the function. a) Using the function above, fill in a chart of the concentration of the drug in the bloodstream for the first 24-hour period after administration at intervals of two hours. Write the concentration accurate to two decimal places as needed. t 0 2 4 6 8 10 12 14 16 18 20 22 24 c(t) b) When will the concentration of the drug fall to a level of 0.5 mg/L? c) When must the next dose of the drug be administered to the patient in order to maintain a concentration above 1 mg/L and below 8 mg/L?

Choose an item your business will sell and find the selling price of that item online from a competitor’s website. Describe the item and include the URL to the item you are selling in your post. Use an internet search engine to find the average markup percentage on this type of item. For example, search the average markup on lawnmowers. State what percentage you found. Use that markup percentage to calculate the cost and dollar markup of the item. Show all calculations.How satisfied are you with your markup? Using several sentences discuss what markup strategy you intend to use. Will you stick with the average industry markup or go with something else? Will you calculate all your markups by hand or use a different strategy to calculate?
