FUNDRAISERS The Band Boosters had custom T-shirts made for homecoming that they plan to sell for $10 each. They paid a $25.90 setup fee and $8.15 per shirt to have the shirts made. How many shirts do they need to sell to break even?
If x represents the number of shirts, write an equation to represent the situation.
Write an equation

mxb67

step-by-step explanation:

answer: the answer is b. i think hope i got it correct

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
