help me to explain this every details

Simple Interest Example: Find the present value of Solution $2,000 which is due at the end D = Fdt of 90 days at 5% simple = P2,000(.05)) discount. = P25 Given: P = F D F = P2,000 = P2,000 25 = P1,975 ta Alternative Solution P = F(1 dt) d = .05 = P2000 (1 0.05) (+)] = P1,975 1 t = - 4
