Question 148023: Can you assist me with this problem, I am not sure about how to set up problem to solve.
The formula for pressure is P p = 5 + (5/d11), where P is in pounds per square inch and d is depth in ft. Find P when d = 11 ft.

Is the equation P+=+5+%2B+5%2F%2811d%29 ?


P=5%2B5%2F%2811%2Ad%29 Start with the given expression.


P=5%2B5%2F%2811%2A11%29 Plug in d=11


P=5%2B5%2F121 Multiply 11 and 11 to get 121.


P=610%2F121 Combine the fractions.


P=5.041 Approximate the fraction


So the pressure is about 5.041 PSI





----------------------------

OR....
Is the equation P+=+5+%2B+5%2Fd ?



P=5%2B5%2Fd Start with the given equation.


P=5%2B5%2F11 Plug in d=11


P=55%2F11%2B5%2F11 Multiply 5 by 11%2F11


P=60%2F11 Combine the fractions.


P=5.4545 Approximate the fraction.


So the pressure is about 5.4545 PSI
