#b. The equation y = 50x + 200 represents the total cost that the contractor will charge for x hours of work.
#c. (1, 250); (2, 300); (3, 350)
So since its a right triangle, we can use the pythagorean theorem, which is
. Since we know that 2 and 3 are our legs and x is our hypotenuse, we can solve the equation as such:

Since √13 can't be further simplified, that is your final answer.
Answer:
15+0.75x
Step-by-step explanation:
x=number of tickets
The mistake is that they subtracted 21 instead of adding it. you would have had to added 21 to the left side to cancel it out and added 21 to the right side to get p= 55
