Answer:
Difference = 81 F
Explanation:
Given that,
High temperature = 78 F
The low temperature of the town is -3F
We need to find the difference between the high and low temperatures for the town last year.
Difference = High temperature - low temperature
= 78 F - (-3F)
= 78 + 3
= 81 F
So, the required difference in temperature is equal to 81 F.
