A charitable organization is planning a benefits concert to generate funds for their projects. Tickets for the event are $10 for lower level seating or $25 for
the higher level seating. The concert hall can seat up to 5000 people. Their
goal is to raise at least $75,000.
Which system of inequalities can be used to determine x, the number of $10
tickets they need to sell, and y, the number of $25 tickets they need to sell to
meet or exceed their goal?
A.
10x + 25y = 75,000
x+y 5000
10x + 25 y 25000
B.
X+ y s 5000
x+y < 5000
C.
10x + 25y > 75,000
D.
x+y 5000
10x + 25 y 275,000

A.10x + 25y = 75,000

Step-by-step explanation:

It's the most logic one and you can use rational thought to make the process out

it is a reproduction.

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
