Substance A decomposes at a rate proportional to the amount of A present. a) Write an equation that gives the amount A left of an initial amount A, after time t. b) It is found that 18 lb of A will reduce to 9 lb in 4.2 hr. After how long will there be only 1 lb left? a) Choose the equation that gives A in terms of Ao, t, and k, where k>0. O A. A(t) = Ao - kt O B. A(t) = A, e kt kt OC. A(t) = A D. A(t) = A, e - kt b) There will be 1 lb left after hr. (Do not round until the final answer. Then round to the nearest whole number as needed )
