Then divide the total number of eggs by the number of eggs cleaned per minute to find how long the owner spends cleaning them up: 60 eggs / 4 eggs / minute = 15 minutes. Then find the total time the owner spends cleaning up toilet paper: 7 rolls * 30 minutes / roll = 210 minutes. Finally, add that amount to the egg cleaning time to find the total cleaning time: 210 minutes + 15 minutes = 225 minutes. The answer: 225.
