Q: Kyle makes $3200.00 every month. His monthly bills include $1250 for rent, $150 on utilities, $400 into retirement & savings accounts, $300.00 on groceries/eating out, $200 for insurance and $200 for miscellaneous expenses. If he's looking at buying a car with a monthly car payment of $350 how much does that leave for gas and maintenance?
A: Kyle's monthly bills are 1250 + 150 + 400 + 300 + 200 + 200 = $2,500.00. He makes $3200 and his bills are $2500 so that leaves 3200 - 2500 = $700.00. If he buys a car with a monthly car payment of $350 then that leaves 700 - 350 = $350.00 left over for gas and maintenance. The answer is 350.
Question: A school does a yearly tree planting activity. This year, the 4th graders planted a total of 30 trees while 5th graders planted twice as many. The 6th graders planted 30 fewer than thrice the number of trees planted by the 5th graders. How many trees did they plant altogether?
Answer: The 5th graders planted 30 x 2 = 60 trees. Thrice the number of trees planted by the 5th graders is 60 x 3 = 180. So, the 6th graders planted 180 - 30 = 150 trees. Therefore, they planted a total of 30 + 60 + 150 = 240 trees. The answer is 240.
[Question]Bill needs to soak his clothes for 4 minutes to get rid of each grass stain and 7 additional minutes to get rid of each marinara stain. If his clothes have 3 grass stains and 1 marinara stain, how long does he need to soak them?
[Answer]First find the total soaking time to get rid of the grass stains: 4 minutes / stain * 3 stains = 12 minutes. Then add the soak time for the marinara to find the total soak time: 12 minutes + 7 minutes = 19 minutes. The answer is 19.

Question: In a classroom there are 30 students. 1/3 of them are boys. Among the girls, 40% own dogs, 20% own a cat, and the rest have no pets. How many girls in the class have no pet?
Answer: 2 / 3 students are girls because 1 - (1 / 3) = 2 / 3. 20 students are girls because 30 x (2 / 3) = 20. 40% of the girls don't have any pets because 100 - 40 - 20 = 40. 8 girls in class have no pets because 20 x .4 = 8. The answer is 8.
Q: In a section of the forest, there are 100 weasels and 50 rabbits. Three foxes invade this region and hunt the rodents. Each fox catches an average of 4 weasels and 2 rabbits per week. How many rabbits and weasels will be left after 3 weeks?
A:
3 foxes catch 4 weasels each every week for a total of 3 * 4 = 12 weasels. 12 weasels are caught every week for 3 weeks for a total of 12 * 3 = 36 weasels. 3 foxes catch 2 rabbits each every week for a total of 3 * 2 = 6 rabbits. 6 rabbits are caught every week for 3 weeks for a total of 6 * 3 = 18 rabbits. There were originally 100 weasels so now there are 100 - 36 = 64 weasels left. There were originally 50 rabbits so now there are 50 - 18 = 32 rabbits left. There are 64 + 32 = 96 weasels and rabbits left. The answer is 96.
