Based on the probability estimates in the table, the expected value can be calculated by multiplying the number of employees by their respective probabilities and adding them up. 
(65 x 0.1) + (75 x 0.15) + (80 x 0.25) + (90 x 0.4) + (100 x 0.1) = 8.5 + 11.25 + 20 + 36 + 10 = 85. Therefore, the best choice is C.
