Noah’s age is twice Joe’s age. If Joe is 6 years old, how old will Noah be after 10 years?

Noah’s age is 2 * 6 =

<<2*6=12>>12 years old. After 10 years Noah will be 12 + 10 = 22 years old. #### 22 In one month in the Smith house, Kylie uses 3 bath towels, her 2 daughters use a total of 6 bath towels, and her husband uses a total of 3 bath towels. If the washing machine can fit 4 bath towels for one load of laundry, how many loads of laundry will the Smiths need to do to clean all of their used towels? The total number of bath towels used in one month is 3 + 6 + 3 = <<3+6+3=12>>12 bath towels The number of loads of laundry the Smiths need to do is 12 / 4 = <<12/4=3>>3 loads #### 3 Dan is digging graves for a family killed by COVID-19. If it takes Dan 3 hours to dig an adult grave and 2 hours to dig a child's grave, how long does it take him to dig 5 adult graves and one child's grave? First find the total amount of time Dan spends digging adult graves: 3 hours/grave * 5 graves = <<3*5=15>>15 hours Then add the time to dig the child's grave to find the total time he spends digging: 15 hours + 2 hours = <<15+2=17>>17 hours #### 17 Brad’s zip code consists of five numbers that add up to 10. The first and second numbers are the same. The third number is zero. The fourth number is double the first number. The fourth and fifth numbers add up to 8. What is Brad’s zip code? The five numbers add up to 10, so the first three numbers add up to 10 - 8 = <<10-8=2>>2. The third number is 0, so the first two numbers add up to 2 - 0 = <<2-0=2>>2. The first and second numbers are equal, so they are both 2 / 2 = <<2/2=1>>1. The fourth number is double the first number, so it is 2 * 1 = <<1*2=2>>2. The fifth number is 8 - 2 = <<8-2=6>>6. Thus, Brad’s zip code is 11026. #### 11026 Carson leans over the railing at the zoo to get the perfect selfie and falls into the combined wombat and rhea enclosure. There are 9 wombats and 3 rheas. If each wombat claws him 4 times and each rhea claws him once, how many times does he get clawed? First find the total number of times the wombats claw him: 9 wombats * 4 claws/wombat = <<9*4=36>>36 claws Then add the number of times the rheas claw him to find the total: 36 claws + 3 claws = <<36+3=39>>39 claws #### 39 Sixteen boys and 14 girls attended Simon's birthday party. Three-fourths of the boys and 6/7 of the girls brought gifts. How many of those who attended did not bring gifts? 16 x 3/4 = <<16*3/4=12>>12 boys brought gifts. So, 16 -12 = <<16-12=4>>4 boys did not bring gifts. 14 x 6/7 = <<14*6/7=12>>12 girls brought gifts. So, 14 - 12 = <<14-12=2>>2 girls did not bring gifts. Therefore, a total of 4 boys + 2 girls = <<4+2=6>>6 people did not bring gifts. #### 6 Bill is trying to count the toddlers at his daycare, but they keep running around. He double-counts 8 toddlers and misses 3 who are hiding. If Bill thinks he counted 26 toddlers, how many are there really? First subtract the 8 toddlers Bill double-counted from his count: 26 toddlers - 8 toddlers = <<26-8=18>>18 toddlers Then add the 3 toddlers he missed to find the real count: 18 toddlers + 3 toddlers = <<18+3=21>>21 toddlers #### 21 Nina has two pairs of shoes. She bought one of them for $22, and the second one was 50% more expensive. How much did Nina pay for both pairs of shoes? The second pair of shoes was 50/100 * 22 = $<<50/100*22=11>>11 more expensive. That means that the second pair's price was 22 + 11 = $<<22+11=33>>33. So for both pairs of shoes, Nina paid 33 + 22 = $<<33+22=55>>55. #### 55 Nicki spent the last year running a lot. For the first half of the year, she ran a total of 20 miles per week. For the second half of the year, she increased the mileage to 30 miles per week. How many miles total did she run for the year? Each half of the year consists of 52 / 2 = <<52/2=26>>26 weeks. For the first half of the year, Nicki ran a total of 20 * 26 = <<20*26=520>>520 miles. For the second half of the year, Nicki ran a total of 30 * 26 = <<30*26=780>>780 miles. For the entire year, Nicki ran a total of 520 + 780 = <<520+780=1300>>1,300 miles. #### 1300 Quinn's library was hosting a summer reading challenge. For every 5 books you read, you a coupon for a free donut at a nearby bakery. Quinn decided he could read 2 books a week for 10 weeks total. How many free donuts would Quinn be eligible for? Quinn will read 2 books per week for 10 weeks so 2*10=<<2*10=20>>20 books If he reads 5 books, he gets a free donut. So if he reads 20/5 = 4 free donuts #### 4
