Xander's water bottle contains 15.4 oz of water, and he is drinking 0.5 oz of water per second. Leon's water bottle contains 5.4 oz of water, and he is adding 0.75 oz of water each second. Which inequality could be used to find the number of seconds (s) it will take for Xander's water bottle to have a fewer number of ounces than Leon's water bottle?

• 15.4 + .5s > 5.4 + 7.5s

• 15.4 - .5s > 5.4 + 7.5s

• 15.4 - .5s < 5.4 + 7.5s

• 15.4 + .5s < 5.4 + 7.5s
