Kate saved $27 in March. She saved $13 in April and $28 in May. Then Kate spent $49 on a keyboard and $5 on a mouse. How much money does Kate have left?
Let's think: The total amount of money saved is $27 + $13 + $28 = $68. The total cost of the two products is $49 + $5 = $54. Kate has $68 − $54 = $14 left.. The answer is: 14.

The local school is holding a big fair to raise money for 5 classes that want to go on a trip. 150 people came to the party and paid a total of $368 for entrance tickets. There was a raffle which brought in $343. The sale of cakes and drinks brought $279. At the end of the fair, the principal of the school shared the money raised between the 5 classes. How much money did each class receive?
Let's think: First, let’s calculate the total amount of money collected, which is 368 + 343 + 279 = $990. Let us now share this sum between the 5 classes: 990 / 5 = $198.. The answer is: 198.

Four adults with 32 teeth went to the dentist for a checkup after realizing they were having severe tooth pain. They were found to have different numbers of damaged teeth, and each person had some teeth removed. The first person had 1/4 of all his teeth removed, and the second person had 3/8 of his teeth removed, the third person had half of his teeth removed, while the last person only had 4 teeth removed. What's the total number of teeth removed at the dental clinic?
Let's think: The first person had 1 / 4 of all his teeth removed, a total of 1 / 4 * 32 = 8 teeth. The second person had 3 / 8 of his teeth removed, meaning 3 / 8 * 32 = 12 of his teeth were removed. Together, the first and the second person had 12 + 8 = 20 teeth removed in total. The third person had half of his teeth removed, which were 1 / 2 * 32 = 16 teeth. The first three people had a total of 20 + 16 = 36 teeth removed from their mouth. The last person only had 4 teeth removed, bringing the total number of teeth removed at the dentist clinic to be 36 + 4 = 40 teeth.. The answer is: 40.

Police officer A patrols 36 streets in 4 hours. His colleague, officer B, patrols 55 streets in 5 hours. How many streets will both officers patrol in one hour?
Let's think:
Officer A patrols 36 streets / 4 hours = 9 streets / hour. Officer B patrols 55 streets / 5 hours = 11 streets / hour. Together officer A and B patrol 9 streets / hour + 11 streets / hour = 20 streets / hour.. The answer is: 20.
