Answer:
D. $29.40
Explanation:
Calculation for the mean cost per customer for the performance
Using this formula
Mean cost per customer=[(Number of tickets purchased*Relative frequency)]*Performance cost
Let plug in the formula
Mean cost per customer=[(1*0.20)+(2*0.45)+(3*0.10)+(4*0.20)+(5*0.05)]*$12
Mean cost per customer=(0.2+0.9+0.3+0.8+0.25)*$12
Mean cost per customer=2.45*$12
Mean cost per customer=$29.40
Therefore the mean cost per customer for the performance will be $29.40
