A manufacturer of video games sells each copy for $21.27. The manufacturing cost of each copy is $15.78. Monthly fixed costs are $7500. During the first month of sales of a new game, how many copies must be sold in order for the manufacture to break even (that is, in order for the total revenue to equal the total cost)?

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.

add a pic of the graph, then ill edit this "answer" and solve it for you : 3

step-by-step explanation:

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
