Answer:

Sela estimated the sum to be 114; the actual sum is 112.97.  

Step-by-step explanation:

Let's find the rounded sum and the actual sum, as follows:

Rounding each number to the nearest whole:

76.6 ⇒ 77

25.5 ⇒ 26

10.87 ⇒ 11

Sum = 77 + 26 + 11

Sum = 114

Actual sum:

Actual sum = 76.6 + 25.5 + 10.87

Actual sum = 112.97

Sela estimated the sum to be 114; the actual sum is 112.97.
