Understand the equation: Understand the given equation. $\newline$ The equation $P = 14.7 + (f / 22.5)$ represents the total pressure $P$ in pounds per square inch at $f$ feet below the ocean's surface. To find the pressure at the ocean's surface, we need to consider the depth $f$ to be $0$ feet because the ocean's surface is the starting point where depth is measured from.
Substitute value of f: Substitute the value of $f$ as $0$ into the equation. $\newline$ Since we are looking for the pressure at the ocean's surface, we set $f = 0$ . $\newline$ $P = 14.7 + (0 / 22.5)$
Perform the calculation: Perform the calculation. $\newline$ Now we calculate the value of $P$ when $f$ is $0$ . $\newline$ $P = 14.7 + (0 / 22.5) = 14.7 + 0 = 14.7$
