A1.1.3 Linear Inequalities

A storage tank at Kestrel Farms holds 860 gallons of water and drains at a constant rate of 35 gallons per minute. The amount of water, in gallons, in the tank t minutes after draining begins is $860 - 35 t$ . A level sensor works only while the tank holds at least 300 gallons and at most 650 gallons.

Part A. Eitan, a farm worker, models the times when the sensor works with the compound inequality $300 \leq 860 - 35 t \leq 650$ . Complete the solution of the inequality. $\leq t \leq$
