Answer:
The total amount of ticket sales on this day is $1530.
Explanation:
From the information given, the total amount of ticket sales would be equal to the result of multiplying the number of regular tickets sold for its price plus the number of matinee tickets sold for its price, which would be:
Ticket sales=15R+12M, where
R= number of regular tickets sold= 70
M= number of matinee tickets sold= 40
Now, you can replace these values on the formula to find the total amount of ticket sales on this day:
Ticket sales=15(70)+12(40)
Ticket sales=1050+480
Ticket sales=1530
According to this, the answer is that the total amount of ticket sales on this day is $1530.
