When she paid for the earrings the cashier added a 7.5% sales tax to the discounted price. What is the percent change between the original price and the discounted price? Round your answer to the nearest tenth of a percent

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.

is there supposed to be a diagram or a graph for this one? ?
