polynominal
An appliance company sells x machines
total revenue R in dollars, given by
polynominal R=221.19x-0.2x^2.
What is revenue from sale of 273 machines. I do not know what I am
suppose to multiply first. Please help.
R = 221.19x - 0.2x^2
R = 221.19 (273) - 0.2(273)^2
R = 221.19 (273) - 0.2(74,529)
R = ?
To find the revenue from the sale of 273 machines, you need to substitute the value of x (273) into the polynomial equation provided, which is:
R = 221.19x - 0.2x^2.
Let's break down the equation step by step to understand how to solve it.
1. Start by substituting the value of x (273) into the equation:
R = 221.19(273) - 0.2(273)^2.
2. Now, simplify each part of the equation:
R = 221.19 * 273 - 0.2 * (273^2).
3. Calculate the value inside the parentheses first:
273^2 = 273 * 273 = 74,529.
R = 221.19 * 273 - 0.2 * 74,529.
4. Perform the multiplications:
R = 60,057.87 - 14,905.8.
5. Finally, subtract the second value from the first:
R = 45,152.07.
Therefore, the revenue from the sale of 273 machines is $45,152.07.
