f. If the selling price increases by $4 per unit and the sales volume decreases by 200 units, what would be the net operating income? g. If the variable cost per unit increases by $2, spending on advertising increases by $1,000, and unit sales increase by 240 units, what would be the net operating income? h. What is the break-even point in unit sales? i. What is the break-even point in dollar sales?

1-Due to an increase in labor rates, the company estimates that variable expenses will increase by $3 per ball next year. If this change takes place and the selling price per ball remains constant at $25, what will be the new CM ratio and break-even point in balls? 2. Refer to the data in (2) above. If the expected change in variable expenses takes place, how many balls will have to be sold next year to earn the same net operating income, $90,000, as last year? 3. Refer again to the data in (2) above. The president feels that the company must raise the selling price of its basketballs. If Northwood Company wants to maintain the same CM ratio as last year, what selling price per ball must it charge next year to cover the increased labor costs?

Now suppose that annual unit sales, variable cost, and unit price are equal to their respective expected values—that is, there is no uncertainty. Determine the company's annual profit for this scenario. Round answer to a whole number, if needed.$

using the price p=20 - .05x, use the Revenue function to find the marginal Revenue function R'(x), Find a. R'(100)= b. R'(175)= c. R'(250)= The marginal Revenue R'(x) approximates how the revenue will change on the sale of the next item. a. Given R(100) = 642 and R'(100)= 18 then R(101) ≈   b. Given R(400) = 16,250 and R'(400)= -10 then R(401) ≈   c. Given R(1000) = 3500 and R'(1000) = 3 then R(1001) ≈
