Lens Junction sells lenses for $47 each and is estimating sales of 15,000 units in January and 18,000 in February. Each lens consists of 2 pounds of silicon costing $2.40 per pound, 3 oz of solution costing $2 per ounce, and 30 minutes of direct labor at a labor rate of $19 per hour. Desired inventory levels are: Jan. 31 Feb. 28 Mar. 31 Beginning inventory \begin{tabular}{|l|r|r|r|} \hline Finished goods & 4,000 & 4,800 & 5,100 \\ \hline Direct materials: silicon & 8,000 & 9,000 & 9,100 \\ \hline Direct materials: solution & 11,000 & 11,900 & 12,900 \\ \hline \end{tabular} Prepare a sales budget, production budget, direct materials budget for silicon and solution, and a direct labor budget for the months of January and February. Show any calculations using Excel formulas (there are point deductions for not using Excel functions, and if you use Excel functions the assignment is much easier because budgets generally have programmatic elements that reflect mathemetical assumptions). Hint: the order of the listed budgets is intentional, budgets logically build off one another
