WebOECD 301B is an aqueous aerobic biodegradation test that determines the ready biodegradability of a material by measuring CO2 evolution during biodegradation in continuously aerated bottles. As one of the first-tier tests among OECD 301-303 standard methods, it aims at screening readily biodegradable materials normally within 28 days. WebA = P * (1 + r * t) where A is the final amount, P is the principal (initial amount), r is the annual interest rate as a decimal, and t is the time period in years. Plugging in the values we have: A = 4000 * (1 + 0.051 * 10) We can simplify the expression in the parentheses: A = 4000 * (1 + 0.51) A = 4000 * 1.51.
