The described situation represents a normal distribution.
For a normally distributed distribution, P(X < x) = P(z < (x - mean) / standard deviation))
P(x > 100) = 1 - P(z =< 100) = 1 - P(z < (100 - 80) / 12.12) = 1 - P(z < 1.6502) = 1 - 0.95055 = 0.04945 = 4.9%
Therefore, the required percentage of the customers expected to get free gifts is 4.9%.
