David, a professional wrestler, went on a very strict liquid diet for 26 weeks to lose weight. When he began the diet, he weighed in at a healthy 240 pounds and during the diet, he consistently lost 2.3% of his body weight each week. His weight loss can be modeled by the function W(t)=240(0.977)t where W is his weight in pounds and t is the time in weeks that he has been on the diet. Use the function to answer the following questions. Determine how much David weighed after 9 weeks. Round your answers to the nearest tenth of a pound. After 9 weeks, David weighed pounds. Determine how long it took for David to weigh in at 143.84 pounds. Round your answer to the nearest week. David will weigh in at 143.84 pounds after weeks.
