Zara bought 2.4 pounds of grapes and a watermelon that cost $5.28. The total cost of the fruit was $7.32. Which describes a way to determine x, the price per pound for the grapes?
Solve for x in the equation 2.40
5.28 = 7.32
Divide 7.32 by 2.4 and then subtract 5.28 from the quotient.
Subtract 5.28 from 7.32 and then divide the difference by 2.4.
Solve for x in the equation 2.4 (2+5.28) = 7.32.

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.
