Please refer to the interest rate tables for numerical answers. (5 Points) (b) Write an expression in terms of the unknown X: What is the present equivalent value P of Cash Flow (B). You are free to decompose Cash Flow (B) further if you want to. Just write down the expression like "e.g. Pg = X (P/F, 4%, 10) + X/2 (P/A, 4 %, 5) - 4,000 " You don't need to calculate the final numerical answer. (10 Points)
