A water tank has 22 gallons of water. It begins to receive 26 gallons per hour for a number of hours. If the tank needs to fill to at least 516 gallons, which of the following is the minimum number of hours the tank should continue filling?
min = (516 -22 -26*some)/26
LHS: min - hours still needed RHS: water missing /26 since we only need hours = 1/26 water added
