Q. Set up an equation describing the following situation, using x for the independent variable and y for the dependent variable: 

Betty wants to start a business selling cookies. She'll need $17,000 to convert her kitchen into a commercial kitchen capable of handling large-scale cookie production. After converting her kitchen, she will spend $2000 per year on ingredients and other supplies, and will make $6000 per year from cookie sales.



x = 4000y + 17000
y = 17000x + 6000
y = 4000x + 17000
y = -2000x + 6000
y = 2000x + 17000

Q. Ten days ago, some scientists started running an experiment where they linearly increase the temperature of a particular liquid over a long period of time. It's a top secret experiment, so please don't blab about it to your friends. Anyway, when the experiment started, the temperature of the liquid was -12° F. Today the temperature of the liquid is 3° F, and in ten more days the temperature of the liquid will be 18° F. How do they know it will be 18° F in ten days? Oh yeah...they also invented a time machine. 

After how many days from the start of the experiment was the temperature of the liquid equal to 0° F?
