X = # of perfomances
y = total amount of money
Income: y = 7500x
Expense: y = 5900x + 88000
Substitution:
7500x = 5900x + 88000
1600x = 88000
x = 55
y = 7500(55) = $412,500
55 performances are needed to break-even.
The answer should be A, if he marked it up 70% just multiply 66 by 1.7 for your answer.
B, y-intercept, because since the x coordinate for the ordered pair is 0, it is showing y-intercept
1) is the correct answer because you just have to arrange them by degree
So in a proportion 23.4 over 5.49 equals 1 over o and multiply 5.49•1=23.4o
5.49=23.4o divide by 23.4 on both sides and that equals 4.26 per oz
