Solve the problem.
-The long jump record, in feet, at a particular school can be modeled by f(x) = 18.1 + 2.5 ln (x + 1) where x is the number of years since records began to be kept at the school. What is the record for the long jump 16 years after
Records started being kept? Round your answer to the nearest tenth.
A) 24.9 ft
B) 20.6 ft
C) 25.0 ft
D) 25.2 ft

To find the long jump record 16 years after records began, substitute x = 16 into the given function: f(16) = 18.1 + 2.5 ln(16 + 1) = 18.1 + 2.5 ln(17). Calculating this gives approximately 25.2 feet.
