Blanchard Company manufactures a single product that sells for $180 per unit and whose total variable costs are$135 per unit. The company’s annual fixed costs are $562,500. Management targets an annual pretax income of$1,012,500. Assume that fixed costs remain at $562,500. Compute the (1) unit sales to earn the target income and (2) dollar sales to earn the target income.

Blanchard Company manufactures a single product that sells for $180 per unit and whose total variable costs are$135 per unit. The company’s annual fixed costs are $562,500. Use this information to compute the company’s (a) contribution margin, (b) contribution margin ratio, (c) break-even point in units, and (d) break-even point in dollars of sales.

The formula of water is $\mathrm{H}_{2} \mathrm{O}.$ Which of the following is indicated by this formula? Explain your answer. There are two hydrogen atoms and one oxygen atom per water molecule.

Apple produces tablet computers for sale. Identify some of the variable and fixed product costs associated with that production.

Blanchard Company manufactures a single product|that sells for $\$ 180$ per unit and whose total variable costs are $\$ 135$ per unit. The company's annual fixed costs are $\$ 562,500$. The sales manager predicts that annual sales of the company's product will soon reach 40,000 units and its price will increase to $\$ 200$ per unit. According to the production manager, the variable costs are expected to increase to $\$ 140$ per unit but fixed costs will remain at $\$ 562,500$. The income tax rate is $20 \%$. What amounts of pretax and after-tax income can the company expect to earn from these predicted changes? (Hint: Prepare a forecasted contribution margin income statement as in Exhibit 21.21.)

A manufacturer uses activity-based costing to assign overhead costs to products. Budgeted cost information for selected activities for next year follows. Form two cost pools and compute activity rates for each of the cost pools.

$$\begin{matrix} \text{Activity} & \text{Expected Cost} & \text{Cost Driver} & \text{Expected Usage of Cost Driver}\\ \text{Purchasing}\ldots\ldots\ldots & \text{\$135,000} & \text{Purchase orders} & \text{4,500 purchase orders}\\ \text{Cleaning factory} \ldots\ldots\ldots & \text{32,000} & \text{Square feet} & \text{5,000 square feet}\\ \text{Providing utilities}\ldots\ldots\ldots & \text{65,000} & \text{Square feet} & \text{5,000 square feet}\\ \end{matrix}$$

Use Fermat’s principle to find the path of a light ray through a medium of index of refraction proportional to the given function. $x^{1 / 3}$ Hint: In the last integration, let $x=u^{3}$.

(a) Determine if the given Heaviside function is differentiable at c. (b) Give a physical interpretation of each function.

$$u_{3}(t)=\left\{\begin{array}{ll} 0 & \text { if } \quad t<3 \\ 1 & \text { if } \quad t \geq 3 \end{array} \text { at } c=3\right.$$

A rope with mass $m_{r}$ is attached to a block with mass $m_{b}$. The block rests on a frictionless, horizontal surface. The rope does not stretch. The free end of the rope is pulled to the right with a horizontal force $\overrightarrow{\mathbf{F}}$. (a) Draw force diagrams for the rope and the block, noting that the tension in the rope is not uniform. (b) Find the acceleration of the system in terms of $m_{b}$, $m_{r},$ and F. (c) Find the magnitude of the force the rope exerts on the block. (d) What happens to the force on the block as the rope's mass approaches zero? What can you state about the tension in a light cord joining a pair of moving objects?

Find the area of the circle.

A parallel-plate capacitor with vacuum between its horizontal plates has a capacitance of $25.0 \mu \mathrm{F}$. A nonconducting liquid with dielectric constant 6.50 is poured into the space between the plates, filling up a fraction f of its volume. (a) Find the new capacitance as a function of f. (b) What should you expect the capacitance to be when f = 0? Does your expression from part (a) agree with your answer? (c) What capacitance should you expect when f = 1? Does the expression from part (a) agree with your answer?

A so-called 7-way lamp has three 60-watt bulbs which may be turned on one or two or all three at a time, and a large bulb which may be turned to 100 watts, 200 watts or 300 watts. How many different light intensities can the lamp be set to give if the completely off position is not included?
