The concession stand at a sports arena sells large 3-pints sodas. on an average night four sodas are sold each minute. how many gallons of soda are sold per hour?

The first thing you must know to answer this is that 1 pint = .125 gallons. That means that each 3 pints drink sold is .375 gallons (.125*3=.375). Now, the stand sells 4 of these .375 gallon drinks a minute. Therefore they would sell 240 of these an hour, since there are 60 minutes in an hour. You can calculated this using this equation [(4 drinks/1min)*(60min/1hour)]. Now we can multiply the number of drinks sold in an hour by the amount of soda in each drink to get the total gallons sold per hour. The equation for this is 240*.375. This equals 90. Therefore the answer is 90 gallons per hour.
