Given the temperatures:
High, T1 = 94 degrees
Low, T2 = 73 degrees
Let's find the difference between the temperatures.
To find the difference, let's subtract the low temperature high temperature
We have:
Difference = T1 - T2
Difference = 94 - 73 = 21 degrees.
Therefore, the difference between the forecasted high and low temperatures is 21 degrees.
ANSWER:
21 degrees
