Brenda wants to create a formula for computing the total cost of any restaurant dinner bill that includes 6% sales tax, a 15% tip on the pre-tax amount, $5 for parking, and $2.50 for a coat check. Write a simplified expression that can be used to calculate the total cost of a dinner that costs d dollars before tax and tip are added. Simplify the expression.

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.

answer: x=60
