Answer:31.1 degrees Fahrenheit
Explanation:
To find the difference in temperatures between the day and night in the town, you need to subtract the nighttime temperature from the daytime temperature. Here's a step-by-step solution:
Step 1: Identify the temperatures
The daytime temperature is 13.2°F.
The nighttime temperature is -17.9°F.
Step 2: Set up the subtraction
To find the difference, subtract the nighttime temperature from the daytime temperature:
Difference = Daytime temperature - Nighttime temperature
Difference = 13.2°F - (-17.9°F)
Step 3: Deal with the double negative
To simplify the subtraction, let's deal with the double negative. Minus (-) multiplied by minus (-) results in a positive number:
Difference = 13.2°F + 17.9°F
Step 4: Perform the addition
Now, add the temperatures:
Difference = 13.2°F + 17.9°F
Step 5: Calculate the difference
Now, perform the addition:
Difference = 31.1°F
