Teagan saved 200 pennies in her piggy bank. Rex has a mason jar filled with 100 nickels. Toni has 330 dimes stashed inside a giant mug. How much money did the three kids save altogether?
Let's think: Teagan saved 1 cent (.01) x 200 = $2. Rex has 5 cents (.05) x 100 = $5. Toni has 10 cents (.10) x 330 = $33. Together, the three kids saved $2 + $5 + $33 = $40.. The answer is: 40.

The Great Pyramid of Giza was the tallest man-made structure on earth for almost 4000 years. It is 20 feet taller than 500 feet, and 234 feet wider than it is tall. What is the sum of the height and width of the Great Pyramid of Giza in feet?
Let's think: The height is 20 feet taller than 500 feet, or 500 + 20 = 520 feet. The structure is 234 feet wider than it is tall, or a width of 520 + 234 = 754 feet wide. Therefore, the sum of the height and width of the Great Pyramid of Giza is 520 + 754 = 1274 feet.. The answer is: 1274.

Janeth bought 5 bags of round balloons with 20 balloons in each bag. She also bought 4 bags of long balloons with 30 balloons in each bag. While blowing up the balloons, 5 round balloons burst. How many balloons are left?
Let's think: Janeth bought 5 x 20 = 100 round balloons. She bought 4 x 30 = 120 long balloons. So, she has a total of 100 + 120 = 220 balloons. Since 5 round balloons burst, then there are only 220 - 5 = 215 balloons left.. The answer is: 215.

The file, 90 megabytes in size, downloads at the rate of 5 megabytes per second for its first 60 megabytes, and then 10 megabytes per second thereafter. How long, in seconds, does it take to download entirely?
Let's think:
The first 60 megabytes take 60 / 5 = 12 seconds. There are 90 - 60 = 30 remaining megabytes. The remaining 30 megabytes take 30 / 10 = 3 seconds. And 12 + 3 = 15 seconds.. The answer is: 15.
