[tex]\begin{gathered} \text{Subtract 15 in both sides of the equation:} \\ 100-15=15-15+\frac{5}{13}d \\ \\ 85=\frac{5}{13}d \\ \\ \text{Multiply both sides of the equation by 13/5:} \\ \frac{13}{5}\cdot85=\frac{13}{5}\cdot\frac{5}{13}d \\ \\ 221=d \\ \\ d=221 \end{gathered}[/tex]

Then, The pressure of sea water is 100 pounds per square foot at a depth of 221 feet below the surface of the water

2. Find the pressure of the water (P) when d=80

[tex]\begin{gathered} P=15+\frac{5}{13}(80) \\ \\ P=15+\frac{400}{13} \\ \\ P=\frac{195+400}{13} \\ \\ P=\frac{595}{13} \\ \\ P=45.8 \end{gathered}[/tex]
