The flow-rate of your current sink faucet is 2.1 gallons per minute. If you purchase a fancy low-flow faucet for $261, the flow rate would decrease by 34%. Assuming you use your faucet for an average of 1,178 minutes per month and water costs $0.007 per gallon, compute the payback period (in months) of such a purchase.
Round your answer to the nearest tenth of a month (tenth place).
