Answer:

Mike estimated the difference to be 72
The actual difference is 72.74

Explanation:

When mike rounded, 79.44 became 79 and 6.7 became 7

79.44 rounds to 79 because 0.44 is less then 0.5
6.7 rounds to 7 because 0.7 is greater then 0.5
so 79 - 7 = 72

The actual difference is 79.44 - 6.7 = 72.74

79.44
- 6.70
------------

72.74
