Question

A school custodian used vinegar to clean various surfaces. The instruction in a reference manual read "place 4 ounces of vinegar in a one gallon container. Add distilled water to make one gallon of cleaner. Mix thoroughly before each use."

After mixing and using 5 gallons of the mixture, the custodian decided the mix was not strong enough and increased the amount of vinegar to six ounces while making the cleaning solution. What is the total amount of cleaner the custodian made if all of the vinegar in a 64 ounce bottle was used? Explain your reasoning.
