Answer:
The horse-drawn carriage tour company can expect to take in $6960 when the charge per customer is $60.
Step-by-step explanation:
p(2) = 120 -2·2 = 116 . . . . . expected number of customers per day
c(2) = 50 +5·2 = 60 . . . . . . charge per customer
Then ...
(p·c)(2) = p(2)·c(2) = 116·60 = 6960 . . . . revenue for the day
