MY NOTES ASK YOUR TEA Marginal Cost, Revenus, and Profit for Producing LCD TVs A company manufactures a series of 20-in. flat-tube LCD televisions. The quantity x of these sets demanded each week is r to the wholesale unit price p by the following equation. p = -0.007x + 170 The weekly total cost (in dollars) incurred by Pulsar for producing x sets is represented by the following equation. Find the following functions (in dollars) and compute the following values. C(x) = 0.000001x - 0.02x + 130x + 75,000 (a) Find the revenue function R. R(x) = Find the profit function P. P(x) = (b) Find the marginal cost function C'. C'(x) = Find the marginal revenue function R'. R'(x) =
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
