Mike Westfield is analyzing ordinary annuity investment by calculating the sum of the present values of its expected cash flows. Assuming an interest rate greater than 0%, which of the following would decrease the present value of the investment? a. Using a lower interest rate. b. The riskiness of the investment's cash flows decreases. c. Reducing the size of the annual payments by half (e. g., reducing the annual payment from $100 to $50) while doubling the number of annual payments (e. g., doubling the number of annual payments from 10 to 20). d. Doubling the size of the annual payments (e. g., doubling the annual payment from $100 to $200) while reducing the number of annual payments by half (e. g., reducing the number of annual payments from 10 to 5). e. None of the above will decrease the present value of the investment.

During the year, the delph company had no beginning or ending inventories and it started, completed, and sold only two jobs—job d-75 and job c-100. it provided the following information related to those two jobs: job d-75: molding fabrication total direct materials cost $ 375,000 $ 325,000 $ 700,000 direct labor cost $ 200,000 $ 160,000 $ 360,000 machine-hours 15,000 5,000 20,000 job c-100: molding fabrication total direct materials cost $ 300,000 $ 250,000 $ 550,000 direct labor cost $ 175,000 $ 225,000 $ 400,000 machine-hours 5,000 25,000 30,000delph had no overapplied or underapplied manufacturing overhead during the year. assume delph uses a plantwide overhead rate based on machine-hours.1-a. compute the predetermined plantwide overhead rate.1-b. compute the total manufacturing costs assigned to job d-70 and job c-200.1-c. if delph establishes bid prices that are 150% of total manufacturing costs, what bid price would it have established for job d-70 and job c-200? 1-d. what is delph's cost of goods sold for the year? assume delph uses departmental overhead rates based on machine-hours.2-a. compute the predetermined departmental overhead rates.2-b. compute the total manufacturing costs assigned to job d-70 and job c-200.2-c. if delph establishes bid prices that are 150% of total manufacturing costs, what bid price would it have established for job d-70 and job c-200? 2-d. what is delph's cost of goods sold for the year?
