14. Earning a graduated commission as follows: 5.25% of the first $7,000 of sales : 6.75% on the next $10,000 : 7.25% on any
amount over $17,000. Calculate the total commission on $23,500
of total sales

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.

the answer is y = 11.54

hope this : )

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
