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

Question

anonymous · Answer

$$26x + 22 = 516$$
This is the written form of the question, so let's subtract 22 from both sides and divide by 26!

$$x=\frac{ 516-22 }{ 26}$$

Hope that helps!
