An operating log indicates that the average flow through a pump for ten hours is 285 gallons per minute. The following week, the same output is measured as 340 gallons per minute. What is the percent change?

  • applied math -

    Percent change is measured by the difference divided by the original capacity.

    difference = new - old = 340-285=55 gpm
    old capacity = 285 gpm
    So
    Percentage change = 55/285*100%
