Answer: Yes, the rate went up by 2.73 dollars per hour.

The graph has slope 20 since each time x goes up by 1, y goes up by 20. The unit rate for the graph is 20 dollars an hour. You can use the slope formula to determine this as well.

If she charged $250 for 11 hours, then the unit rate is now 250/11 = 22.73 dollars an hour. She increased her hourly rate by 2.73 dollars.

Answer:

She didn't charge her unit rate because her unit rate it $20 per hour but she charged $22.73 instead of $20, which increased her price by $2.73.

Step-by-step explanation:

Dividing 20/1 you get 20. Dividing 250/11 you get 22.73 which isn't the unit rate. Just divide y by x.
