Carla, Amy, and Bill all work as lawn mowers. They each drive a separate lawnmower. The total cost of lawn mowing for Amy, Bill, and Carla is displayed in the table that follows.

$$\begin{array}{cccc} \begin{array}{c} \text { Quantity of } \\ \text { lawns mowed } \end{array} & \begin{array}{c} \text { Amy's } \\ \text { total cost } \end{array} & \begin{array}{c} \text { Bill's } \\ \text { total cost } \end{array} & \begin{array}{c} \text { Carla's } \\ \text { total cost } \end{array} \\ 0 & \$ 0 & \$ 0 & \$ 0 \\ 1 & 20 & 10 & 2 \\ 2 & 35 & 20 & 7 \\ 3 & 45 & 30 & 17 \\ 4 & 50 & 40 & 32 \\ 5 & 52 & 50 & 52 \\ 6 & 53 & 60 & 82 \end{array}$$

a. Determine the marginal costs of Amy, Bill, and Carla and draw each of their marginal cost curves. b. Which parties have rising marginal costs, falling marginal costs, and constant marginal costs?

Katie mows lawns in the summer to earn extra money. She started with 3 lawns, and she now mows 12 lawns in her fourth summer. Graph the line that models the growth of Katie's business over time. What is the slope of the graph? What does it represent?

Gale's grade in science for the term is determined by the average of five test grades. His firs four grades are 80, 95, 78, and 90. In order to get a B for the term, Gale needs to have an average of 84. What grade must Gale get on the next test to get a B for the term? Write an inequality to solve. Show your work.

For a science fair demonstration you would like to create a diffraction pattern similar to that shown in Figure 28-44. If you plan to shine a laser pointer $(\lambda=652 \mathrm{~nm})$ through a pair of slits that are separated by $175 ~\mu \mathrm{m}$, how far away from the slits should you place the screen?

Venus Candy Company budgeted the following costs for anticipated production for September $2010$:

$$\begin{array}{lrlr}\text { Advertising expenses } & \$ 275,000 & \text { Production supervisor wages } & \$ 132,000 \\ \text { Manufacturing supplies } & 15,000 & \text { Production control salaries } & 35,000 \\ \text { Power and light } & 44,000 & \text { Executive officer salaries } & 280,000 \\ \text { Sales commissions } & 300,000 & \text { Materials management salaries } & 38,000 \\ \text { Factory insurance } & 26,000 & \text { Factory depreciation } & 21,000\end{array}$$

Prepare a factory overhead cost budget, separating variable and fixed costs. Assume that factory insurance and depreciation are the only factory fixed costs.

The Hurley Hat Company manufactures baseball hats. Hurley's primary customers are sporting goods stores that supply uniforms to youth baseball teams. Following is Hurley's income statement for 2016:

$$\begin{array}{c} \textbf{HURLEY HAT COMPANY}\\ \text{Income Statement}\\ \text{Year Ended December 31, 2016}\\ \hline \end{array}$$

$$\begin{array}{lr} \text{Sales Revenue}&\$1,500,00\\ \text{Cost of Goods Sold}&\underline{700,000}\\ \text{Gross Profit}&800,000\\ \text{Selling and Administrative}&\underline{500,000}\\ \text{Operating Income}&\underline{\underline{\$300,000}}\\ \end{array}$$

In 2016, Hurley produced and sold 200,000 baseball hats. Of the Cost of Goods Sold, $150,000 is fixed; 80% of the Selling and Administrative Expenses are fixed. There were no beginning inventories on January 1, 2016. The company is operating at 100,000 hats below full production capacity and is considering increasing advertising to increase sales to the production capacity level. The marketing director predicts that an additional$100,000 expenditure for advertising would increase sales to 300,000 hats per year. The sales manager has been negotiating with buyers for several national sporting goods retailers and recommends the company expand production capacity to 400,000 hats in order to secure long-term contracts. The expansion is expected to increase fixed manufacturing costs by $200,000 per year. Additionally, the retailers are requesting a higher-quality hat, and the changes to the hat materials and manufacturing process would increase variable manufacturing costs by$1 per hat for the additional 200,000 hats. (The original 200,000 hats manufactured and sold would not be affected by this change.) Requirements

1. Use the data from the 2016 income statement to prepare an income statement using variable costing. Assume no beginning or ending inventories. Calculate the contribution margin ratio. Round to two decimal places.
2. Prepare an absorption costing income statement assuming the company increases advertising and production and sales increase to 300,000 hats.
3. Refer to the original data. Prepare an absorption costing income statement assuming the company increases capacity and sales and production increases to 400,000 total hats.
4. Which option should the company pursue? Explain your reasoning.
