Please look up "volume of a cylinder."
The formula for the volume of a cylinder of radius r and height h is
V = pi*r^2*h
So, if r = 1.5 m and h = 10 m, the volume of the tank is
V = pi*(1.5 m)^2*(10 m) = 70.69 cubic meters.
If x is the number of hours Patricia needs to babysit, the inequality is

Therefore, since she has already saved $60,

Thus, the inequality that models the question is 60+5x>=200
