Question

p(0)=1atm,p(33) = 2 and so on find the pressure at 180 feet

Answer 1

I put in the wrong number the pressure is 140

Answer 2

i'm not sure about this (if it requires some formulas), but i used extrapolation:
X Y
0 1
33 2
140 y
therefore,
(y-1)/(y-2)=(140-0)/(140-33)
y=5.24

so there,, =)
