A typical cup of coffee contains about 82 mg of caffeine and every hour approximately 19% is metabolized and eliminated. Write the definition of a function named k that expresses the amount of caffeine in the body in mg as a function of t, the number of hours since the coffee was consumed. How much caffeine is in the body after 7 hours? mg A 80 mg of a vaccine is given to a patient to prevent measles. The vaccine leaves the body at a rate of 4.8% per hour. Define a function g that gives the mass of the vaccine remaining in the body, V, in terms of the number of hours, n since the vaccine was administered. How much of the vaccine remains in the body 24 hours after it was administered? mg Use your graphing calculator to determine how many hours passed before there were only 5mg of the vaccine remaining in the body. hours
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
