The biomass B(t) of a fishery is the total mass of the members of the fish population at time t. It is the product of the number of individuals N(t) in the population and the average mass M(t) of a fish at time t. In the case of guppies, breeding occurs continually. Suppose that at time t=4 weeks the population is 822 guppies and is growing at a rate of 50 guppies per week, while the average mass is 1.2 grams and is increasing at a rate of 0.14 g/week. At what rate is the biomass increasing when t=4? (Round your answer to one decimal place.)
