Tom receives a $12 allowance per month. In the first week, he spends a third of it; in the second week, he spends a quarter of what he has left. How much money does he have left to finish the month?

The first week he spends: $12 * 1/3 = $

<<12*1/3=4>>4. So he has $12 - $4 = $<<12-4=8>>8 left. In the second week, he spends $8 x 1/4 = $<<8*1/4=2>>2. So Tom has $8 - $2 = $<<8-2=6>>6 left to finish the month. #### 6 Granger has five times as many spots as his brother, Cisco. But Cisco has 5 less than half as many spots as his cousin, Rover. If Rover has 46 spots, how many spots do Granger and Cisco have combined? If Rover has 46 spots, then half as many spots as Rover has is 46/2=<<46/2=23>>23 spots. If Cisco has 5 less than half as many spots as Rover has, then Cisco has 23-5=<<23-5=18>>18 spots. If Granger has five times as many spots as Cisco, then Rover has 18*5=<<18*5=90>>90 spots. Thus, the total combined number of spots that Rover and Cisco have is 90+18=<<90+18=108>>108 spots. #### 108 Jon drinks a bottle of water that is 16 ounces every 4 hours for the 16 hours he is awake. Twice a day he also drinks a bottle that is 25% larger than those bottles. How much fluid does he drink a week? He drinks 16/4=<<16/4=4>>4 of the small bottles each day That is 4*16=<<4*16=64>>64 ounces The larger bottles are 16*.25=<<16*.25=4>>4 ounces larger So the large bottles are 16+4=<<16+4=20>>20 ounces So he drinks 20*2=<<20*2=40>>40 ounces of those a day So he drinks 64+40=<<64+40=104>>104 ounces a day That means he drinks 104*7=<<104*7=728>>728 ounces a day #### 728 The ratio of boys to girls in a classroom is 3:5. If there are 4 more girls than boys, how many students are in the classroom? Since the ratio of boys to girls is 3:5, then the class is divided into 3 + 5 = <<3+5=8>>8 parts. The girls have 5 - 3 = <<5-3=2>>2 parts more than the boys. Since 2 parts are equal to 4, then 1 part is equal to 4/2 = 2 students. Hence, there are 8 parts x 2 = <<8*2=16>>16 students. #### 16 Amanda had 10 notebooks. This week, she ordered 6 more and then lost 2. How many notebooks does Amanda have now?

She is selling 5 posters per day at school. Two posters per day are her large posters that sell for $10. The large posters cost her $5 to make. The remaining posters are small posters that sell for $6. They cost $3 to produce. How much profit, in dollars, does Laran make per 5-day school week? The profit made for each large poster is $10 - $5 = $<<10-5=5>>5. Each day Laran earns $5 * 2 = $<<5*2=10>>10 from selling large posters. The profit made for each small poster is $6 - $3 = $<<6-3=3>>3. Each day Laran earns $3 * 3 = $<<3*3=9>>9 from selling small posters. Laran makes a total profit of $10 + $9 = $<<10+9=19>>19 per day. For a 5 day school week, Laran makes a profit of 5 * $19 = $<<5*19=95>>95. #### 95 Carter is a professional drummer. He goes through 5 sets of drum sticks per show.
