Plug in t=5: Plug in t=5 into the function to check if f(5) equals 355. f(5) = 800(0.85)^(5)Calculate power of 0.85: Calculate the value of 0.85 raised to the power of 5. (0.85)^(5) ≈ 0.4437053125Multiply 800 by 0.4437053125: Multiply 800 by 0.4437053125 to find f(5). f(5) ≈ 800 * 0.4437053125Perform multiplication: Perform the multiplication to find the value of the computer after 5 years. f(5) ≈ 800 * 0.4437053125 ≈ 355
