A large pharmaceutical company uses the function f(x)=1.582x- 3029 to model the amount of​ money, in billions of​ dollars, it spends each year on research and​ development, where x corresponds to the year. Use the function to predict the amount of money it will spend in 2025.

To predict the amount of money the pharmaceutical company will spend in 2025, we need to substitute x = 2025 into the function f(x) = 1.582x - 3029.

f(2025) = 1.582 * 2025 - 3029
= 3200.85 - 3029
= 171.85

Therefore, the pharmaceutical company is predicted to spend $171.85 billion in research and development in 2025.
