Answer:
$7,350.00
Explanation:
To find out the total amount of money, you need to know the total amount of tickets sold.
So, find out what 20% of 350 is for the second hour and add it to the 350 from the first hour
350 x 0.20 = 70
350 + 70 = 420 total tickets
now you multiply 420 by the amount of money per ticket in order to know the price for all the tickets in both hours
420 x 17.50 = 7,350 dollars total
