Suppose the cost and the demand for a daily product is: C=10 d(p) = D(1 - w(p)) = 200-10p What is the total contribution (profit) based on the optimal price?

22) Which of the following expressions can be used to calculate break-even sales revenue with the contribution-margin ratio (CMR)? A) CMR x fixed costs B) (Sales revenue -variable costs) +CMR. O Fixed costs - CMR. D) CMR - fixed costs. E) (Fixed costs + variable costs) x CMR.

22. Which of the following statements is true if total fixed costs decrease while the sales price per unit and variable cost per unit remain constant?     The contribution margin increases.     The breakeven point increases.     The contribution margin decreases.     The breakeven point decreases.

Answer the question on the basis of the following marginal utility data for products X and Y. Assume that the prices of X and Y are $4 and $2, respectively, and that the consumer's income is $18.
