A young sumo wrestler, named Akebono, decided to go on a special high-calorie diet to gain weight rapidly. He started at 90 kg and gained weight at a linear rate. After 8 months, he weighed 138 kg. a. Express this problem as a linear function with weight, W, as a function of time, t. Write the equation, W(t), in slope-intercept form. Answer: W(t) = b. Using the equation from part (a), how much does Akebono weigh after one year? Answer: kg c. Akebono wants to start wrestling when he weighs 270 kg. From when he began his diet, how long must he stay on his diet to achieve his wrestling aspirations? Use the equation from part (a) to compute your answer. (By the weigh, a baby killer whale is only 180 kg!) Answer: Months
