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.
3x - 4 + x^2 - 1 + 2x^2 - 15
3x^2 + 3x - 20
I wasn't sure if you wanted me to solve for x, but I did anyways.
x ≈ 1.86, or -2.86
Answer:
55+8.5x=123

Answer:
6
Step-by-step explanation:
you add them all up and divide it by how many numbers there are
The probability of getting a <em>country CD</em> out of all the CDs is the number of <em>country CDs</em> divided by the <em>total number of CDs</em> in Dante's Collection.
The <em>total number of CDs</em> in Dante's collection is
.
The total number of <em>country CDs</em> is 12.
So our required probability is
.
In percentage this is 3 divided by 10, and then multiply by 100. We get 30%. Answer choice D is correct.
