A group of 8 friends went to lunch and spent a total of $76, which included the food bill and a tip of $16. They decided to split the bill and tip evenly among themselves.

Which equations and solutions describe the situation? Select two options.

A. The equation 1/8 (x + 16) = 76/8 represents the situation, where x is the food bill.
B. The equation 1/8 (x + 16) = 76 represents the situation, where x is the food bill.
C. The solution x = 60 represents the total food bill.
D. The solution x = 60 represents each friend’s share of the food bill and tip.
E. The equation 8 (x + 16) = 76 represents the situation, where x is the food bill.

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
