Question

the function p(d)=1+d/33 gives the pressure in atmosphere (atm) at depth d in the sea is feet (note that p(0)=1 atm p,33=2 and so on find the pressure at 20 feet

Answer 1

Let depth = 22 ft

Now follow these two steps:
step 1: (depth) divided by 33
step 2: add 1 to your answer from step 1.

Answer 2

1.6?

Answer 3

Well, you'll have 1 + (22/33) which is 1+ 2/3 and that's 1.6666...

So if you round UP you have 1.7. :)
