The temperature at 6:00 A. M. was 0.8°F. By 3:00 P. M., the temperature had increased to 2.4°F. Find the difference between the two temperatures. Draw models to find the difference.

1.6

Explanation:

2.4-0.8=1.6

For the model you can draw a number line that starts at 0.8 and goes to 2.5 by increasing 0.1. Then add an arch between the two numbers for the times it will increase, which will be sixteen times. At the bottom write 16=1.6
