Using the reciprocal services method, which of the following equations represents the correct algebraic expression needed to capture the total costs of a Janitorial Department (J) that includes $350,000 of direct costs and 30% of the Maintenance Department (M) cost and the Maintenance Department that includes $50,000 of direct costs and 50% of the Janitorial Department? (Hint: This equation is derived from the two separate equations representing each department’s costs.) Group of answer choices J = $350,000 + (0.30 ÷ $50,000) + (0.50 ÷ J) J = ($350,000 × 0.30) + ($50,000 × 0.50) + J J = $350,000 – [(0.30 × $50,000) – (0.50 × J)] J = $350,000 + {0.30 × [$50,000 + (0.50 × J)]}

Quick calculate the roi dollar amount and percentage for these example investments. a. you invest $50 in a government bond that says you can redeem it a year later for $55. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage. b. you invest $200 in stocks and sell them one year later for $230. use the instructions in lesson 3 to calculate the roi dollar amount and percentage. (3.0 points) tip: subtract the initial investment from the total return to get the roi dollar amount. then divide the roi dollar amount by the initial investment, and multiply that number by 100 to get the percentage.
