Hi! So to solve this problem, you simply make an equation from the information you are given. If the temperature drops every 2 degrees every hour, then your variable will be the number of hours. Therefore your equation should look like this: 2x=y. To solve for the total amount of degrees for 4 hours, you plug in 4 for your x value and solve for y: 2(4)=y. Your answer should come out to be 8 total degrees.
