Solve the problem.A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 3 seconds, the gauge on the bottle indicates that it contains 18 ounces of water. After it has been filling for 11 seconds, the gauge indicates the bottle contains 58 ounces of water. Let y be the amount of water in the bottle x seconds after the faucet was turned on.
