Use that information to answer the questions that follow. Where necessary, round your answer to the nearest tenth and use "pounds" for the units. Drake graduated from high school and moved away from home to begin college. When he arrived at the school, he was in great shape and ready to go, weighing in at 170 pounds. Eight months later, he was shocked to realize that he had put on 40 pounds and couldn't walk up two flights of stairs without breaking a sweat. He looked back at how his weight changed and recorded it in the table below. Use that table to answer the following questions. Time, t, in months 0 2 3 4 5 6 7 8 Weight, in pounds 170 179 187 194 200 205 207 209 2 Determine Drake's average weight gain per month (Average Rate of Change) for the fall semester (Months 0 to 4). Round your answer to one decimal place. Average Rate of Change = Interpret your answer by completing the sentence below. Be sure to use units in your answer. Drake gained on average per during the fall semester. Determine Drake's average weight gain per month (Average Rate of Change) for the spring semester (Months 4 to 8). Round your answer to one decimal place. Average Rate of Change = Interpret your answer by completing the sentence below. Be sure to use units in your answer. Drake gained on average per during the spring semester. Determine Drake's average weight gain for the entire school year. Round your answer to one decimal place. Average Rate of Change = Interpret your answer by completing the sentence below. Be sure to use units in your answer. Drake gained on average per during his first year of college.

For each page sent or received past the 150 page limit, the customer must pay an overage fee of $0.08 per page. The following expression gives the total cost, in dollars, to send p pages beyond the plan's monthly limit. C = 0.08p + 16.25 If the monthly bill under this plan comes out to be $23.53, what was the total number of pages that were sent or received?
