Transcript text: Homework Question 1, 1.4.55-BE HW Score: $0 \%, 0$ of 6 points Points: 0 of 1 Save The cost $C$ of producing $x$ thousand calculators is given by the equation below. \[ C=-15.2 x^{2}+14,790 x+540,000(x \leq 150) \] The average cost per calculator is the total cost C divided by the number of calculators produced. Write a rational expression that gives the average cost per calculator when $x$ thousand are produced. The rational expression for the average cost is $\square$ (Do not simplify.)

Solution

Solution Steps

To find the average cost per calculator, we need to divide the total cost $ C $ by the number of calculators produced. Since $ x $ is given in thousands, the number of calculators produced is $ 1000x $. Therefore, the average cost per calculator is given by the rational expression $ \frac{C}{1000x} $.

Step 1: Define the Cost Function

The cost $ C $ of producing $ x $ thousand calculators is given by the equation: \[ C = -15.2x^2 + 14790x + 540000 \]

Step 2: Define the Number of Calculators Produced

Since $ x $ is in thousands, the number of calculators produced is $ 1000x $.

Step 3: Calculate the Average Cost per Calculator

The average cost per calculator is the total cost $ C $ divided by the number of calculators produced: \[ \text{Average Cost} = \frac{C}{1000x} \]

Step 4: Substitute the Cost Function into the Average Cost Formula

Substitute $ C = -15.2x^2 + 14790x + 540000 $ into the average cost formula: \[ \text{Average Cost} = \frac{-15.2x^2 + 14790x + 540000}{1000x} \]
