Claudia offers art classes to kids and charges $10.00 for her one-hour class. If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make?

Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20/2 =

<<20/2=10>>10 kids She has 20 kids on Saturday and 10 kids on Sunday for a total of 20+10 = <<20+10=30>>30 kids She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10*30 = $<<10*30=300.00>>300.00 #### 300 It starts raining at 7:00 and pours heavily until its stops at 17:00 on a particular day. On the second day, the rain takes 2 more hours than it took on the first day to stop. On the third day, the rain pours for twice the amount of time it took on the second day. Calculate the total time it was raining in the three days. On the first day, it rained for 17:00 - 7:00 = 10 hours On the second day, it 10 hours + 2 hours = <<10+2=12>>12 hours for the rain to stop It rained for 2 * 12 hours = <<2*12=24>>24 hours on the third day. In the three days, it was raining for 24 hours + 12 hours + 10 hours = <<24+12+10=46>>46 hours. #### 46 There are 20 stickers on a page. If you have 12 pages of stickers but lose one of the pages, then how many stickers would you have? After losing one of the pages you have 12 - 1 = <<12-1=11>>11 pages of stickers. If each page has 20 stickers on it, you have 11 x 20 = <<11*20=220>>220 stickers. #### 220 Janina spends $30 each day for rent and uses $12 worth of supplies daily to run her pancake stand. If she sells each pancake for $2, how many pancakes must Janina sell each day to cover her expenses? Janina spends $30+$12=$<<30+12=42>>42 each day for her pancake stand. She must sell $42/$2=<<42/2=21>>21 pancakes each day to cover her expenses. #### 21 Allie has 9 toys, which are in total worth $52. If we know that one toy is worth $12, and all the other toys have the same value, how much does one of the other toys cost? Allie has 9 - 1 = <<9-1=8>>8 toys of the same value. Without the value of the one $12 toy, all 8 other toys are worth in total 52 - 12 = $<<52-12=40>>40. That would mean, that one of the other toys is worth 40 / 8 = $<<40/8=5>>5. #### 5 A family went out to see a movie. The regular ticket costs $9 and the ticket for children is $2 less. They gave the cashier two $20 bills and they received a $1 change. How many children are there if there are 2 adults in the family? They gave the cashier $20 x 2 = $<<20*2=40>>40. Since a $1 change was returned, this means the tickets cost $40 - $1 = $<<40-1=39>>39. Two adult tickets cost $9 x 2 = $<<9*2=18>>18. So, $39 - $18 = $<<39-18=21>>21 was spent for the children's tickets. Each child's ticket costs $9 - $2 = $<<9-2=7>>7. Therefore, there are $21/$7 = <<21/7=3>>3 children. #### 3 Julio has four bottles of orange soda and seven bottles of grape soda in his fridge. His friend Mateo has a bottle of orange soda and 3 bottles of grape soda in his fridge. If the amount of beverage in each bottle is 2 liters, how many more liters of soda does Julio have? Julio has 4 * 2 = <<4*2=8>>8 liters of orange soda Julio also has 7 * 2 = <<7*2=14>>14 liters of grape soda. Julio therefore has a total of 8 + 14 = <<8+14=22>>22 liters of soda The amount of orange soda that Mateo has is 1 * 2 = <<1*2=2>>2 liters of orange soda In addition, Mateo has 3 * 2 = <<3*2=6>>6 liters of grape soda. In total, Mateo has 2 + 6 = <<2+6=8>>8 liters of soda. This means that Julio has 22 - 8 = <<22-8=14>>14 liters more of soda #### 14 Braelynn has 24 knives in her kitchen and twice as many teaspoons as knives. If she bought 1/3 as many additional knives and 2/3 as many additional teaspoons, what would be the total number of cutlery pieces she has in her kitchen? Braelynn bought 1/3*24 = <<1/3*24=8>>8 more knives to add to her kitchen. The total number of knives in her kitchen is now 24+8 = <<24+8=32>>32 knives In her kitchen, Braelynn currently has 2*24 = <<2*24=48>>48 teaspoons. When she buys 2/3 times more teaspoons, the total number increases by 2/3*48 = <<2/3*48=32>>32. So she will have a total of 32+48 = <<32+48=80>>80 teaspoons. The total number of cutlery pieces Braelynn will have in her kitchen is 80+32 = <<80+32=112>>112 #### 112 John buys 30 ducks for $10 each. They weigh 4 pounds and he sells them for $5 per pound. How much profit did he make? He bought the ducks for 30*10=$<<30*10=300>>300 He sold each duck for 4*5=$<<4*5=20>>20 So he sold all the ducks for 30*20=$<<30*20=600>>600 So he made a profit of 600-300=$<<600-300=300>>300 #### 300 This evening in the nighttime sky over Texas, Mars can be seen until 12:10 AM. Jupiter does not appear until 2 hours and 41 minutes later, and Uranus does not appear until 3 hours and 16 minutes after Jupiter makes its first appearance. How many minutes after 6:00 AM does Uranus first appear in the evening sky over Texas this evening? Jupiter appears 2 hours and 41 minutes after 12:10 AM, which can be calculated in two parts; 2 hours after 12:10 AM is 12:10+2:00 = 2:10 AM. And an additional 41 minutes after 2:10 AM is 2:10+0:41 = 2:51 AM. Uranus appears 3 hours and 16 minutes after 2:51 AM, which can be calculated in two parts: 3 hours after 2:51 AM is 2:51+3:00 = 5:51 AM. And 16 minutes after 5:51 AM is 5:51+0:16 = 5:67 AM = 6:07 AM. Thus, 6:07 AM is 7 minutes after 6:00 AM. #### 7
