Danica conducts a science experiment with a mixture that freezes at temperatures of -20°F and below. Danica wants to cool this mixture down, but does not want it to
freeze
She puts the mixture into a freezer that will lower its temperature by 3.5°F
every hour
• When she puts the mixture into the freezer, its temperature is 22°F.
Which inequality matches how long, in h hours, Danica could leave this mixture in the
freezer before it starts to freeze?

Suppose you are an avid reader and are looking to save money on the cost of books instead of paying about $20 for each book, you decide to look into purchasing a kindle for $120 you can purchase e-books for about $5 each 1. find the slope-intercept equation for the cost of the hard copy of books using x to represent the number of books 2. find the slope-intercept equation for the cost of the kindle with cost of e-books using x to represent the number of books
