Question 1198795
Instead of doing it for you, I'll do one exactly like it instead" 
<pre>
The pressure (P) on a diver in the water varies directly as the depth (d). If
the pressure is 4.95 psi when the depth is 9 ft, what is the pressure when the
depth is 16 ft?

The pressure (P) on a diver in the water varies directly as the depth (d).

{{{P=k*d}}}

If the pressure is 4.95 psi when the depth is 9 ft,

{{{4.95=k*9}}}

{{{4.95/9=(k*9)/9}}}

{{{0.55=k}}}

what is the pressure when the depth is 16 ft?

Substitute 0.55 for k in {{{P=k*d}}}

{{{P=0.55*d}}}

Substitute 16 for d

{{{P=0.55*16}}}

{{{P=8.8}}}

Answer: 8.8 psi

Now do yours the same way.
