Answer this question:Michael was watching a TV show, which was aired for 1.5 hours. During this time, there were 3 commercials, which lasted 10 minutes each. How long (in hours) was the TV show itself, not counting commercials?
Each commercial lasted 10 minutes, so three commercials lasted 3 * 10 = 30 minutes. The show was aired for 1.5 hours, and 30 minutes is 0.5 of an hour, so without the commercials, the show was 1.5 - 0.5 = 1 hour long.
The answer is 1.

Answer this question:Katie's mother wants to get granola bars for all the kids to eat after Katie's soccer game. There will be 30 kids playing soccer, including Katie. Katie's mother wants to get 2 granola bars for each kid, since the bars are not that big and she figures the kids will be very hungry. Each box of granola bars has 12 bars in it. How many boxes should Katie's mother buy?
There will be 30 kids playing soccer and 2 granola bars for each kid, 30 x 2 = 60 granola bars total. Each box of granola bars has 12 in it, so Katie's mother needs 60 granola bars / 12 bars each box = 5 boxes.
The answer is 5.

Answer this question:Peter carried $500 to the market. He bought 6 kilos of potatoes for $2 per kilo, 9 kilos of tomato for $3 per kilo, 5 kilos of cucumbers for $4 per kilo, and 3 kilos of bananas for $5 per kilo. How much is Peter's remaining money?
The price of potatoes is 6 * 2 = $12. The price of tomatoes is 9 * 3 = $27. The price of cucumbers is 5 * 4 = $20. The price of bananas is 3 * 5 = $15. The total price Peter spent is 12 + 27 + 20 + 15 = $74. The amount left with Peter is $500 - $74 = $426.
The answer is 426.

Answer this question:Andy harvests all the tomatoes from 18 plants that have 7 tomatoes each. If he dries half the tomatoes and turns a third of the remainder into marinara sauce, how many tomatoes are left?
First find the total number of tomatoes harvested: 18 plants * 7 tomatoes / plant = 126 tomatoes. Then divide that number by 2 to find how many tomatoes are left undried: 126 tomatoes / 2 = 63 tomatoes. Then divide that number by 3 to find how many tomatoes are turned into sauce: 63 tomatoes / 3 = 21 tomatoes. Then subtract that number from the number of undried tomatoes to find the remaining number of tomatoes: 63 tomatoes - 21 tomatoes = 42 tomatoes.
The answer is 42.
