Question: Sam is stocking up on canned tuna. He got 9 cans at the supermarket, and had 5 coupons for 25 cents off a single can per coupon. He paid $20 and got $5.50 in change. How many cents does a can of tuna cost?
Answer with step-by-step thinking: His total without the coupons was $20 - $5.50 = $14.50. He had 5 coupons that each saved him 25 cents, so the full price of all the tuna is $14.50 + 5 * $0.25 = $15.75. He bought 9 cans of tuna, so each can costs $15.75 / 9 = $1.75. As 1 dollar has 100 cents 1.75 * 100 = 175 cents.
So the answer is 175.


Question: 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?
Answer with step-by-step thinking: 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.
So the answer is 47.


Question: Chelsea has 24 kilos of sugar. She divides them into 4 bags equally. Then one of the bags gets torn and half of the sugar falls to the ground. How many kilos of sugar remain?
Answer with step-by-step thinking:
Each bag has 24 / 4 = 6 kilos of sugar. 6 / 2 = 3 kilos of sugar falls to the ground. 24 - 3 = 21 kilos of sugar remains.
So the answer is 21.
