The volleyball team at West View High School is comparing T-shirt companies where they can purchase their practice shirts. The two companies, Shirt Box and Just Tees, are represented by this system of equations where x is the number of T-shirts and y is the total cost of the T-shirts. y = 10.5x

y = 7.5x + 30

How many T-shirts would the volleyball team need to purchase from each company for the total cost to be equal?

For the total cost to be the same for both companies, the volleyball team would need to purchase
T-shirts from each company for a total of $
for each company

this is answer of 144 cubic meters

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
