Rounding 83 to the nearest ten gives us 80. Rounding 67 to the nearest ten gives us 70. 
Then, we can estimate the total number of push-ups by multiplying 80 by 70. 
This gives us:
80 x 70 = 5600 
Therefore, the best choice is C. Round 83 to 80 and round 67 to 70. Then estimate the number of push-ups by multiplying 80 by 70 and removing the last digit.
80 x 70 = 5600
Therefore, Linda did approximately 5600 push-ups during that period.
