Answer:
x=6,y=7
Step-by-step explanation:
In a coordinate pair it is assumed that the first number is x, and the 2nd is y.
The error of percentage is the amount of error over the original amount.
In this case it is 22/95 (not 22 over 77 because 77 is not the original amount they expected to sell.
22/95 = .2315 or 23.2% to the nearest tenth of a percent
Perhaps your teacher just wants 23% as an the approximate error.
So your equation would be 37 + 9.70x
114 - 37 would get you 77 dollars. Next, you have to find out how many times 9.70 goes into 77. They would be able to rent the room for a total number of 7 hours because that's how many times 9.70 can fit into 77 evenly.
