Answer: $ 13,305.32
Step-by-step explanation:
Given: Total tickets = 2318
Per ticket cost = $14.35
Cost of all tickets = (Total tickets ) x (Per ticket cost )
= (2318) x (14.35)
= $33,263.3
According to the contract, musician will receive 40% of the money from ticket sales.
So, Musician will receive = 40% of (Cost of all tickets)
= 0.40 x 33263.3
= $ 13,305.32
The musician should receive from ticket sales = $ 13,305.32
