Let say you have 3 products: cake, candy, and bread. The revenue per cake is $8. The revenue per candy is $4. The revenue per bread is $5. Define the number of cake, candy, and bread you are about to produce per day as x, y, and z respectively. The manager wants that the number of candy is at least equal to the total number of cake and bread. What is the correct linear constraint to show this? Group of answer choices z – x – y ≥ 0 x – 2y – z ≥ 0 y – x – z ≥ 0 x – y – z ≥ 0
Suppose you are analyzing the relationship between a firm's advertising budget and its sales volume. Which statement is correct? Group of answer choices Advertising budget is the independent variable. You predict the advertising budget with sales volume. In a scatterplot, sales volume should be on the x-axis and advertising budget should be on the y-axis. Sales volume is the independent variable. thanks

P′(p) = ____ What selling price (in dollars) would have resulted in the largest annual profit? (Round your answer to two decimal places.) p = $____ What would have been the resulting annual profit (in millions of dollars)? (Round your answer to the nearest whole number.) $ ____ million
A company finds that there is a linear relationship between the amount of money that it spends on advertising and the number of units it sells. If it spends no money on advertising it sells 250 units. For each additional $2500 spent, an additional 25 units are sold. 1. If x is the amount of money that the company spends on advertising, find a formula for y, the number of units sold as a function of x. y= 2. How many units does the firm sell if it spends $25,000 on advertising? = ____ units 3. How many units does the firm sell if it spends $50,000 on advertising? = ____ units 4.

It is known that a certain company sells each kg of the product it manufactures at $80, it is also known that the total manufacturing cost "CT" is given by the function CT=(1/1000)x2 +100 , where "x" are the kg of product produced. a) How many units of "x" must the company sell to break even? Value = 100 points.b) How many units of "x" is the optimal quantity that should be sold to optimize the producer's profit? Value = 100 points.c) How many monetary units does that optimal profit for producers amount to? (remember, you will have to prove it mathematically either by the method of the first or by the method of the second derivative). Value = 100 points.
