Solve the problem.
-The function $P ( d ) = 1 + \frac { d } { 33 }$ gives the pressure, in atmospheres (atm), at a depth $d$ feet in the sea. Find the pressure at 42 feet.
A) $\frac { 25 } { 11 } \mathrm {~atm}$
B) $\frac { 43 } { 33 } \mathrm {~atm}$
C) $\frac { 14 } { 11 } \mathrm {~atm}$
D) $\frac { 3 } { 11 } \mathrm {~atm}$

To find the pressure at 42 feet, substitute $d = 42$ into the function: $P(42) = 1 + \frac{42}{33} = 1 + \frac{14}{11} = \frac{25}{11} \mathrm{~atm}$.
