Item 9 A company that offers tubing trips down a river rents tubes for a person to use and “cooler” tubes to carry food and water. A group spends $270 to rent a total of 15 tubes. Write a system of linear equations that represents this situation. Use xx to represent the number of one-person tubes rented and yy to represent the number of cooler tubes rented. How many of each type of tube does the group rent?

You would need to know how much it cost to rent each type of tube in order to solve this problem.

One of the equations would be xx+yy=15
The number of single tubes plus the number of cooler tubes is 15.

If you know how much each tube cost, simply put the cost in front of the xx/yy and set it equal to 270$. For example, if the single tubes cost 15$ and the cooler tubes cost 20$, then the equation would be 15xx+20yy=270
