Question

Tanker boats cannot be in the bay when the depth of water is less or equal to 25 feet. Set up an inequality and solve it graphically to determine all points in time, t, on the interval 0 less than or equal to t less than or equal to 24 when tankers cannot be in the bay. Round all times to the nearest tenth of an hour.

Would the inequality be x+20 less than or equal to 24?
