Johnson has a sack of potatoes. He gives Gina 69 potatoes, gives Tom twice as much potatoes as he gave Gina and gives one-third of the amount of potatoes he gave Tom to Anne. How many potatoes does he have left if the sack contains 300 potatoes? Let's answer step by step:
He gives twice 69 potatoes to Tom, which is 69 * 2 = 138 potatoes. He gives one - third of 138 potatoes to Anne, which is 138 * (1 / 3) = 46 potatoes. In total, he has given out 69 + 138 + 46 = 253 potatoes. He initially had 300 potatoes so he now has 300 - 253 = 47 potatoes left. The answer: 47.
