Quizplus · Accepted Answer

Plugging in d = 200 feet into the given function, we get P = 7.15 atm. Rounding to the nearest whole number gives the answer of 7 atm. Therefore, the best choice is C. Evaluating the function P(200) (by plugging in 200 for d) gives a value of approximately 7 atm. Rounding to the nearest whole number, the answer is C) 7 atm.
