If a range hood removes contaminants at a flow rate of F liters of air per second, then the percent P of contaminants that are also removed from the surrounding air can be modeled by P = 1.05F + 17.64, where F is between and inclusive of 10 and 75. What flow rate F must a range hood have to remove

61% of the contaminants from the air?
