Aeris reads the temperature of a liquid in a lab experiment. The temperature of the liquid is 7.2ºF. After 5 hours, she reads the temperature of the liquid again. The temperature of the liquid is now −1.6°F. Aeris plots the points on a number line to determine the temperature change between these two readings. How much did the temperature decrease? Enter your answer as a decimal in the box.

Step-by-step explanation:
What we know:
• Temperature started as 7.2
• Temperature ended as -1.6
• We need to find the difference
How to solve:
By doing simple subtraction, we can solve this.
Process:
• Write equation                                                   7.2 – (-1.6) = ?
• Simplify                                                               7.2 + 1.6 = ?
• Solve                                                                                 = 8.8
Solution: 8.8 (-8.8’F)
*Note: The temperature decreased by 8.8’F, but it increased/changed by -8.8’F. Be careful of wording.
