The members of West Valley High School's student council are planning this year's school carnival. For the raffle, they plan to order one roll of 150 golden tickets. For the carnival games, they plan to order blue tickets that come in rolls of 200. Based on last year's numbers, they plan to order a total of 1,550 tickets. How many rolls of blue tickets should the student council order?

rolls

The student council plans to order 1,550 tickets in total. They already plan to order one roll of 150 golden tickets, so they need 1,550 - 150 = <<1550-150=1400>>1400 blue tickets.

Each roll of blue tickets contains 200 tickets, so the student council needs to order 1400 / 200 = <<1400/200=7>>7 rolls of blue tickets. Answer: \boxed{7}.

To find out how many rolls of blue tickets the student council should order, we first need to determine how many blue tickets they need in total.

Since they plan to order one roll of 150 golden tickets, we can consider these tickets to be separate from the blue tickets.
Therefore, the total number of blue tickets needed can be calculated by subtracting the number of golden tickets from the total number of tickets:
Total blue tickets = total number of tickets - number of golden tickets
Total blue tickets = 1,550 tickets - 150 golden tickets

Let's calculate this:
Total blue tickets = 1,550 - 150 = 1,400 tickets

Since each roll of blue tickets contains 200 tickets, we can find the number of rolls by dividing the total number of blue tickets by the number of tickets per roll:
Number of rolls of blue tickets = Total blue tickets ÷ Number of tickets per roll
Number of rolls of blue tickets = 1,400 ÷ 200

Let's calculate this:
Number of rolls of blue tickets = 7 rolls

Therefore, the student council should order 7 rolls of blue tickets for the carnival games.

To find out how many rolls of blue tickets the student council should order, we need to determine how many blue tickets are included in 1,550 tickets in total.

Since the student council plans to order one roll of 150 golden tickets, we subtract that number from the total number of tickets to get the number of blue tickets:

1,550 total tickets - 150 golden tickets = 1,400 blue tickets

Next, we need to calculate how many blue tickets are included in one roll of blue tickets. We are given that one roll contains 200 blue tickets.

To find out how many rolls of blue tickets should be ordered, we divide the total number of blue tickets by the number of blue tickets in one roll:

1,400 blue tickets ÷ 200 blue tickets per roll = 7 rolls

Therefore, the student council should order 7 rolls of blue tickets for the carnival games.
