A major concern with Social Security is the possibility that funds will not be available when today’s tax-payers retire to become beneficiaries. According to the Social Security Trustee’s report, an increase of 1.89% in the Social Security payroll tax would keep the account full for the next 75 years. To achieve similar results, benefits would have to be decreased from the current 42% of the ending salary to 29% of the salary.Cindy is relatively new to the workforce. She has 32 years until she can retire. Her current annual salary is $45,000.

1a) Calculate how much Cindy will have to pay in Social Security tax (6.2%) based on this salary.
1b) Calculate how much Cindy will have to pay in Social Security tax if the tax was increased by 1.89%.

2a) Calculate Cindy’s annual Social Security benefit (about 42%) if her salary remains unchanged until she retires (annual average is $45,000).
2b) Calculate Cindy’s annual Social Security benefit if her salary remains unchanged but benefits (based on her annual salary of $45,000) were cut from 42% to 29%.

3) If Cindy were given a choice between the increase in Social Security tax now or the decrease in Social Security benefits when she retires, which would you recommend she choose? Explain your answer thoroughly.

The Plastic Flowerpots Company has two manufacturing departments, molding and packaging. At the beginning of the month, the molding department has 2,000 units in inventory, 70% complete as to materials. During the month, the molding department started 18,000 units. At the end of the month, the molding department had 3,000 units in ending inventory, 80% complete as to materials. Units completed in the molding department are transferred into the packaging department. Cost information for the molding department for the month follows: Beginning work in process inventory (direct materials) $ 1,200 Direct materials added during the month 27,900 Using the weighted-average method, compute the molding department's (a) equivalent units of production for materials and (b) cost per equivalent unit of production for materials for the month. (Round "cost per equivalent unit of production" to 2 decimal places.)
