Mark is looking to buy a total of 12 pieces of fruit at the store. He has already chosen 3 apples. He has also selected a bunch of bananas containing 4 bananas. How many oranges does he need to pick out to have 12 total pieces of fruit? Give the rationale and then the answer.
Let's think step by step. He has 3 apples and 4 bananas, so he has 3 + 4 = 7 pieces of fruit. He needs to buy 12 fruit - 7 fruit = 5 oranges.. The answer is: 5.

Reese had a sum of money in her savings account. The company she used to work with was not doing well which is why she lost her job. So she spent 20% of her savings for her expenses in February, 40% of it in March, and $1500 in April. How much did she have in her savings account if she still has $2900 after spending those amounts? Give the rationale and then the answer.
Let's think step by step. The total percentage of money that Reese spent in February and March is 20% + 40% = 60%. This means the April expenses and the money left in her account make up 100% - 60% = 40% of her savings. Reese had $2900 + $1500 = $4400 for the April expenses and the money left in her account. So, $4400 is equal to 40% which means every 1% is equal to $4400 / 40 = $110. Therefore, Reese originally had $110 x 100 = $11000 in her savings account.. The answer is: 11000.

Julia has $40. She spends half of her money to buy a new game for her phone. She spends a quarter of what she has left on in-game purchases. How much money does she have left? Give the rationale and then the answer.
Let's think step by step. Julia spend $40 / 2 = $20 on the game. After buying the game, she has $40 - $20 = $20 left. She spent $20 / 4 = $5 on in - game purchases. She has $20 - $5 = $15 left.. The answer is: 15.
