Question

Tanya is printing a report. There are 100 sheets of paper in the printer, and the number of sheets p left after t minutes of printing is given by the function p(t) = -8t+100. What is the domain of the function? Explain.

Answer 1

Answer:

12.5 min

Step-by-step explanation: -8 shows that the paper uses 8 pages/minute. You can solve the equation doing 100/8.

You can also find the answer by solving the equation for the value t. Subtract 100 from both sides, and you will get -8t = -100. Then, divide both sides by -8 and you will get 12.5
