Mike paid $13 for three books diego bought 12 books price at the same rate how much did diego pay for 12 bucks explain your reasoning

Diego paid $52 for 12 books.

Step-by-step explanation:

If Mike bought 3 books for $13 that means that a book cost him $ 4.33

$ 13/3 = $ 4.33

And if Diego bought 12 books for the same price, how much did it cost?

An equation called "Rule of 3" is used:

1 book = $ 4.33

12 books = X

The X of the equation is cleared:

X = (12 books * $ 4.33) / 1

X = $ 52 for the 12 books Diego bought.

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.
