Two grams of musk oil are required for each bottle of Mink Caress, a very popular perfume made by a company in Siberia. The cost of the musk oil is $1.80 per gram. Budgeted production of Mink Caress is given below by quarters for Year 2 and for the first quarter of Year 3: small western 16.66 points Year 2 PirstSecond Third Fourth Pirst 90,000 Dudgeted production, in bottles 80,000 110,000 170,000 120,000 Musk oil has become so popular as a perfume ingredient that it has become necessary to carry large inventories as a precaution against stock-outs. For this reason, the inventory of musk oil at the end of a quarter must be equal to 20% of the following quarters production needs. Some 32.000 grams of musk oil will be on hand to start the first quarter of Year 2 Required: Prepare a direct materials budget for musk oil, by quarter and in total, for Year 2.
