As a manager have been asked to estimate the total cost of producing 25 engines in your company. Current engines have an output of 155-hp per engine. 7 years ago, a similar 170 hp engine cost was 6750 KD. Beside that due to extreme competition in the industry, the cost of an engine has decreased with 11% only for 3 intervals of time throughout this period. Total cost consists of engine cost, direct labor cost and other labor-related costs. Pertinent data are as follows: Direct labor cost per 20 KD per hour hour Factory overhead 130% of direct labor Packing costs 70% of direct labor Maintenance costs 10% of engine cost Cost-capacity factor 0.95 Past experience has shown that an 85% learning curve applies to the labor required producing these engines. Maintenance cost will be paid only once at the beginning of the second year. Use the estimated time to complete the 25 engine for the purpose of estimating the direct labor cost. The time to complete the first engine has been estimated to be 72 hours. 1. What is the total cost of the engine? 2. What is the total direct labor cost? 3. What is the total cost of the required production? John wants to know how much he will have in his account in 2 years, if he deposits 420 KWD every month, and increases his deposit by 30 KWD every time he makes a deposit. The interest rate per month is 1% Hint: Use the interest rates tables provided in our Moodle page. Instructions: Use 2 digits in your calculations and reporting the answers. . Do not write commas or apostrophes. Do not write $ (dollar sign) or any other symbol, just write the number. Answers John will have KWD at the end of the project. Write an optional reasoning for your
