The members of Starville High School's student council are planning this year's school carnival. For the raffle, they plan to order one roll of 100 golden tickets. For the carnival games, they plan to order red tickets that come in rolls of 250. Based on last year's numbers, they plan to order a total of 1,600 tickets.

Which equation can the student council use to find how many rolls of red tickets,

r, should they should order?

• 100r+250=1600

• 100(r+250)=1,600

• 250(r+100)=1600

• 250r+100=1600
