uestion 10 6 points Save Answer A mechanical workshop invested in purchasing a semiautomatic machine for $50,000, that expected to generate a net income of $8,000 starting year 4 and then expected to increase by 5% per year thereafter. The useful life of the machine is 20 years. If the workshop's minimum attractive rate of return (MARR) is 10% per year, the standard notation for determining the discounted payback period is: O O O O None of them 0=-50,000+8,000 (P/A, 5%, 10%, np - 3) (P/F, 10%, 3) 0=-50,000 + 8,000 (P/A, -5%, 10%, np - 3) (P/F, 10%, 3) 0=-50,000 + 8,000 (P/A, 5%, 10%, np) 0 = -50,000 + 8,000 (P/A, 5%, 10%, np) (P/F, 10%, 4) 0=-50,000 + 8,000 (P/A, 5%, 10%, np - 4) (P/F, 10%, 4) 0=-50,000 + 8,000 (P/A, -5%, 10%, np - 4) (P/F, 10%, 4) 0=-50,000 + 8,000 (P/A, 5%, 10%, np) (P/F, 10%, 3) Activate Windows
