Karen bakes 50 chocolate chip cookies. She keeps 10 for herself, and she gives 8 to her grandparents. If Karen wants to give everyone in her class cookies, and there are 16 people in her class, how many cookies will each person receive?

After keeping 10 cookies for herself, Karen has 50 - 10 =

<<50-10=40>>40 cookies. After giving cookies to her grandparents, Karen has 40 - 8 = <<40-8=32>>32 cookies. Karen can give each person in her class 32 / 16 = <<32/16=2>>2 cookies. #### 2 Mandy bought 3 packs of black shirts and 3 packs of yellow shirts for her tennis team. The black shirts come in packs of 5, and the yellow shirts come in packs of 2. How many shirts did Mandy buy in all? The number of black shirts is 3 × 5 = <<3*5=15>>15. The number of yellow shirts is 3 × 2 = <<3*2=6>>6. Mandy bought 15 + 6 = <<15+6=21>>21 shirts. #### 21 Tom and his friends were filling up water balloons. Tom filled up 3 times as many water balloons as Luke. Luke filled up one fourth as many balloons as Anthony. If Anthony filled up 44 water balloons, how many did Tom fill up? Luke filled up 44/4=<<44/4=11>>11 water balloons Tom filled up 11*3=<<11*3=33>>33 water balloons #### 33 In Hawaii, they normally get an average of 2 inches of rain a day. With 100 days left in the year, they've gotten 430 inches of rain. How many inches on average do they need to finish the year with the normal average? They need 730 inches of rain a year to average 2 inches a day because 365 x 2 = 730 They need 300 more inches because 730 - 430 = <<730-430=300>>300 They need 3 inches a day because 300 / 100 = <<300/100=3>>3 #### 3 Rose bought her mother one dozen flowers. Two of the flowers are daisies. Three-fifths of the remaining flowers are tulips and the rest are sunflowers. How many sunflowers are there? One dozen of flowers is equal to 1 x 12 = <<1*12=12>>12 flowers. There are 12 - 2 = <<12-2=10>>10 flowers that are not daisies. So, 10 x 3/5 = 6 of the flowers are tulips. Therefore, there are 10 - 6 = <<10-6=4>>4 sunflowers. #### 4 In a forest, there are three anthills. In the first anthill, there are 100 ants, and in each next anthill, there are 20% fewer ants than in the previous one. How many ants are in the third anthill? In the second anthill, there are 20/100 * 100 = <<20/100*100=20>>20 ants less. This means there are 100 - 20 = <<100-20=80>>80 ants in the second anthill. In the third anthill, there are 20/100 * 80 = <<20/100*80=16>>16 ants less compared to the second one. So in the third anthill, there are 80 - 16 = <<80-16=64>>64 ants. #### 64 The number of dishes Sandrine washed was 10 more than the number of bananas Charles cooked. Also, the number of bananas Charles cooked was 3 times the number of pears he picked. If Charles picked 50 pears, how many dishes did Sandrine wash? If the bananas Charles cooked were 3 times the number of pears he picked, then Charles cooked 3*50 = <<3*50=150>>150 bananas. Since all the dishes that Sandrine washed were 10 more than the number of bananas Charles cooked, Sandrine washed 150+10 = 160 dishes. #### 160 Mitch has saved $20000 to finance his boating hobby. A new boat costs $1500 per foot in length. If Mitch needs to keep $500 for a license and registration, and three times that amount for docking fees, how many feet is the longest boat he can buy? Mitch needs to keep 500 * 3 = <<500*3=1500>>1500 for docking fees. Thus, he needs to keep 500 + 3 * 500 = $<<500+3*500=2000>>2000 for license, registration, and docking fees. He has 20000 - 2000 = $<<20000-2000=18000>>18000 left to spend on a boat. Therefore, the longest boat he can buy is 18000 / 1500 = <<18000/1500=12>>12 feet long. #### 12 Bill gets paid $20 every hour he works up to a total of 40 hours, after which he gets paid double that amount per hour. How much does Bill get paid for a 50-hour workweek? Bill makes $20 an hour for the first 40 hours, meaning he gets paid 40*20= <<40*20=800>>800 dollars. For the remaining 10 hours, Bill gets paid double the amount of $20, meaning he makes 20*2=40 dollars an hour. Since he worked 10 hours at that $40 an hour rate, that means he gets paid 10*40= <<10*40=400>>400 dollars for the final 10 hours. In total, this means Bill gets paid 800+400=<<800+400=1200>>1200 dollars for his workweek. #### 1200 Martine has 6 more than twice as many peaches as Benjy. Benjy has one-third as many peaches as Gabrielle. If Martine has 16 peaches, how many does Gabrielle have? Benjy has b peaches. Martine has 6+2b=16 peaches 2b=10 b=5 Then Gabrielle has 5*3=<<5*3=15>>15. #### 15
