Answer:
7.
Explanation:
Let x be each roll of blue tickets the student council orders. They ordered 1 roll of 150 golden tickets, and plan to order blue tickets that come in rolls of 200. They plan to order a total number of, 1550 tickets..
The equation to represent this will be,
150 + 200x = 1550
We need to solve for X =
200x = 1400 =
x = 7
So number of rolls would equal:
7
