1. Exercise 4-6 Compute the Level of Sales Required to Attain a Target Profit [LO6] Ng Corporation produces and sells only one product; its selling price is $120 and its variable cost is $96 per unit. The company's monthly fixed expense is $42,000. Required: 1. Using the equation method, determine the unit sales that are required to earn a target profit before tax of $6,000. Unit Sales: ? units 2. Using the formula method, determine for the dollar sales that are required to earn a target profit before tax of $7,000. Dollar Sales: ? 3. Using the formula method, calculate the number of units that need to be sold to earn an after-tax income of $9,000, assuming a tax rate of 25%. Number of units: ? units 2. Exercise 4-5 Compute the Break-Even Point [LO5] Mackson Products distributes a single product, a woven basket; its selling price is $16 and its variable cost is $12 per unit. The company's monthly fixed expense is $7,700. Required: 1. Compute the company's break-even point in unit sales using the equation method. Break-even point in unit sale ? baskets 2. Compute the company's break-even point in sales dollars using the equation method and the CM ratio.(Do not round intermediate calculations. Round your percentage answer to the nearest whole number.) CM ratio: ? % Break-even point in dollar sales: ? 3Compute the company's break-even point in unit sales using the formula method. . Break-even point in unit sales: ? baskets 4. Compute the company's break-even point in sales dollars using the formula method and the CM ratio. nearest whole number.) CM ratio: ? % Break-even point in dollar sales: ? 3. Exercise 3-8 High-Low Method; Predicting Cost [LO2] The number of blood tests performed and the related costs over the last nine months in Brentline Hospital are given below: Month Blood Tests Performed January 4,360 February 5,500 March 3,450 April 3,140 May 3,282 June 2,400 July 2,918 August 3,700 September 4,080 Blood Test Costs 35,31 $ 0 41,95 $ 0 28,62 $ 6 26,26 $ 2 27,96 $ 1 21,80 $ 0 24,72 $ 3 30,11 $ 6 33,25 $ 0 Required: 1. Using the high-low method, estimate the cost formula for blood tests. (Round cost per unit answer to 2 decimal place) Y = ? + ?X 2. Using the cost formula you derived above, what blood test costs would you expect to be incurred during a month in which 3,290 blood tests are performed? (Round your intermediate calculations answer to 2 decimal places.) Variable cost Fixed cost Total cost $
