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
