Question

underwater, pressure increases 4.3 pounds per square inch(psi) for every ten feet you decend. This is represented by the equation p=0.43d+14.7, where p is the psi and d is the depth in ft. frind the pressure at 200 feet.
a. 215.13psi
b.860 psi
c.11.7 psi

Answer 1

for c i ment 100.7 psi

Answer 2

given
p=0.43d+14.7
we need d to find pressure , d is given as 200
p=0.43*200+14.7
p=86+14.7
p=100.7 psi
option c
