Answer this question:Thomas made 4 stacks of wooden blocks. The first stack was 7 blocks tall. The second stack was 3 blocks taller than the first. The third stack was 6 blocks shorter than the second stack, and the fourth stack was 10 blocks taller than the third stack. If the fifth stack has twice as many blocks as the second stack, how many blocks did Thomas use in all?
The second stack has 7 blocks + 3 blocks = 10 blocks. The third stack has 10 blocks - 6 blocks = 4 blocks. The fourth stack has 4 blocks + 10 blocks = 14 blocks. The fifth stack has 10 blocks x 2 = 20 blocks. In total there are 7 blocks + 10 blocks + 4 blocks + 14 blocks + 20 blocks = 55 blocks.
The answer is 55.

Answer this question:Cristina, John, Clarissa and Sarah want to give their mother a photo album for her birthday. Cristina brings 7 photos, John brings 10 photos and Sarah brings 9 photos. If the photo album has 40 slots available, how many photos does Clarissa need to bring in order to complete the photo album?
Excluding Clarissa, there are 7 + 10 + 9 = 26 photos. Clarissa needs to bring 40 – 26 = 14 photos to complete the photo album.

Answer this question:John and James decided to have a dance-off. John danced for 3 hours and then another 5 hours after taking a 1-hour break. James danced the whole time John was dancing and resting, and then another 1/3 times more hours. How long was their combined dancing time without including John's break time?
John dances 3 + 5 = 8 hours. John's total time is 3 + 5 + 1 = 9 hours. James dances 9 / 3 = 3 hours longer than that. So James dances 9 + 3 = 12 hours. So the total dancing time is 8 + 12 = 20 hours.
The answer is 20.

Answer this question:A state fair charges $5 for a ticket. Two-thirds of the people who buy a ticket will buy deep-fried fair food for $8, one quarter will go on a ride for $4, and one eighth will spend $15 on a souvenir. The fair made $2520 from tickets. How many dollars did they make in all?
The fair made $2520 from tickets, so they had 2520 / 5 = 504 people attend the fair. Two - thirds of those people will buy food, so 504 * 2 / 3 = 336 people will buy food. The fair will make 336 * 8 = $2688 from food. A quarter of the people will go on a ride, so 504 / 4 = 126 people will go on a ride. The fair will make 126 * 4 = $504 from rides. An eighth of the people will buy a souvenir, so 504 / 8 = 63 people will buy souvenirs. The fair will make 63 * 15 = $945 from souvenirs. In all, the fair will make 2520 + 2688 + 504 + 945 = $6657.
The answer is 6657.
