Question

Front-row tickets for a concert cost $60. After every 5 rows, the ticket price goes down $5. Find the total amount of money made by a full house. There are 20 rows. First row has 18 and each row increases by 3.
I have the information. I have this so far:
$60--- row 1-5
$55---row 6-10
$50---row 11-15
$45---row 16-20
I just don't know how to find the total amount of money generated by a full house. I don't get that part.

Answer 10

5 rows have 18 seats, so 5(18) ... so on and so fourth

Answer 11

What do I do once I have all the numbers? Do I add them?

Answer 12

Find the number of seats in each group of rows, then multiply by their price.

Rows 1-5 as 18 seats in row 1, 21 in row 2, 24 in row 3, 27 in row 4 and 30 in row 5. That is a total of 120 seats at $60 each or $7200

repeat this for rows 6-10, hen 11-15 etc and add up all the $ values.
