Explanation Given: The cost and revenue functions for producing and selling x units of graphing calculator are given as C ( x ) = 22 , 500 + 40 x and R ( x ) = 85 x , respectively. Calculation: The break-even point occurs at the point where the graphs of C and R intersects. Thus, it this point can be found by solving the system. { C ( x ) = 22 , 500 + 40 x R ( x ) = 85 x Or, { y = 22 , 500 + 40 x y = 85 x y = 22 , 500 + 40 x …… (1) y = 85 x …… (2) Using the substitution method substitute

The average amount A (in pounds per person) of fish and shellfish consumed in the UnitedStates during the period 1992–2001 can be modeled by A = (3.2x + 260)/(52x + 3800) where x is the number of years since 1992.Rewrite the model so that it has only whole number coefficients. Then simplify the model.

Your cardiac index is your heart's output, in liters of blood per minute, divided by your body's surface area, in square meters. The cardiac index, C(x), can be modeled by 7.644 C(x) = 10 s xs 80, where x is an individual's age, in years. The graph of the function is shown. Use the function to solve Exercises 95–96. 7.644 C(x) = %3D 10 20 30 40 50 60 70 80 90 Age 95. a. Find the cardiac index of a 32-year-old.
