Answer:
$1530
Step-by-step explanation:
First we find the total amount of money earned on regular tickets. To do this multiply 70 tickets (The amount sold) by $15 dollars (The cost of each ticket). We end up with $1050. Then we find the sales for matinee tickets. Multiply 40 (amount of tickets sold) by $12 (price of each ticket). This is $480. Now we add these two numbers together to find the total amount of ticket sales. $1050+$480= $1530.
