A tile factory earns money by charging a flat fee for delivery and a sales price of $0.25 per tile. One customer paid a
total of $3,000 for 10,000 tiles. The equation y-3.000 = 0.25(x - 10,000) models the revenue of the tile factory,
where x is the number of tiles and y is the total cost to the customer
Which function describes the revenue of the tile factory in terms of tiles sold?
What is the flat fee for delivery?

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.
