Question 135967
The function, p(d) = 1 + d/33 gives the pressure, in atmospheres (atm) at a depth d in the sea (d is in feet). Note that p(0) = 1 atm, p(33) = 2, and so on.
:
 Find the pressure at 110 feet.
p(d) = {{{1 + d/33}}}
:
p(110) = {{{1 + 110/33}}}
:
Reduce the fraction to a proper fraction: 110/33 = 3 {{{11/33}}} = 3 {{{1/3}}}
so we have:
p(110) = 1 + 3{{{1/3}}}
:
p(110) = 4 {{{1/3}}} atms
