This quiz is worth $10$ points $($five questions at $2$ points each$).$ You will have $30$ minutes to take this quiz.

The following information$/$data applies to all questions.

Demand is forecasted using the following regression equation:

D $=100+15($t$)$ where $$t$$ is a specified future time period.

The current time period is $0($t$=0).$

The machines used to make this product have a capacity of $50$ units$/$time period.

The company currently has $4$ machines yielding a total capacity of $200$ units$/$time period.

Note: this is a timed quiz. You may check the remaining time you have at any point while taking the quiz by pressing the keyboard combination SHIFT, ALT, and T$...$ Again: SHIFT, ALT, and T$...$
