Sara is 6 inches taller than her brother Joe. Joe is 3 inches taller than his friend Roy. If Roy is 36 inches tall, how tall is Sara?

Roy is

<<36=36>>36 inches tall Joe is 3+36=<<3+36=39>>39 inches tall Sara is 6+39=<<6+39=45>>45 inches tall #### 45 Jane's goal is to exercise 1 hour a day, 5 days a week. If she hits her goal weekly for 8 weeks, how many hours has Jane exercised? Her goal is 1 hour a day for 5 days so on a weekly basis, she exercises 1*5 = <<1*5=5>>5 hours If she works 5 hours a week for 8 weeks then she exercises 5*8 = <<5*8=40>>40 hours in 8 weeks #### 40 Mehki is 10 years older than Jordyn. Jordyn's age is double Zrinka's age. If Zrinka is 6 years old, how many years old is Mehki? Zrinka = <<6=6>>6 years Jordyn = 2 * 6 = <<6*2=12>>12 years Mehki = 12 + 10 = <<12+10=22>>22 years Mehki is 22 years old. #### 22 Louise is baking cakes for a gathering. She needs 60 cakes in total, and has already produced half this many. Today, she calculates how many cakes she has left to make and bakes half this amount. The next day, she again calculates how many cakes she has left to make and bakes a third of this amount. How many more cakes does Louise need to bake? Louise has already produced 60 cakes / 2 = <<60/2=30>>30 cakes. After calculating how many cakes are left, she bakes another 30 cakes / 2 = <<30/2=15>>15 cakes. The next day, she calculates again then bakes another 15 cakes / 3 = <<15/3=5>>5 cakes. She therefore still needs to bake 60 – 30 – 15 – 5 = <<60-30-15-5=10>>10 cakes. #### 10 Rachel is stuffing envelopes. She has eight hours to complete the task, and there are 1,500 envelopes. In the first hour, Rachel stuffs 135 envelopes. The second hour she stuffs 141 envelopes. How many envelopes will Rachel need to stuff per hour to finish the job? Rachel has 1500 - 135 - 141 envelopes = <<1500-135-141=1224>>1224 envelopes remaining to stuff. Rachel has 8 hours - 2 hours = <<8-2=6>>6 hours left to finish the task. Rachel needs to stuff 1224 envelopes / 6 hours = <<1224/6=204>>204 envelopes per hour. #### 204 Lexie and Tom went apple picking. Lexie picked 12 apples and Tom picked twice as many apples. How many apples did they collect altogether? Tom picked 12 x 2 = <<12*2=24>>24 apples Altogether, they picked 12 + 24 = <<12+24=36>>36 apples #### 36 It takes Jason 30 minutes to cut 1 lawn in his neighborhood. If he cuts 8 yards on both Saturday and Sunday, how many hours does he spend cutting grass? He cuts 8 yards on both Saturday and Sunday so that’s 2*8 = <<8*2=16>>16 yards It takes him 30 minutes to cut 1 yard so it takes him 30*16 = <<30*16=480>>480 minutes There are 60 minutes in 1 hour and it takes him 480 minutes so that’s a total of 480/60 = <<480/60=8>>8 hours #### 8 Bonny just bought her 13th pair of shoes, which is 5 less than twice as many pairs of shoes as Becky owns. Bobby has 3 times as many pairs of shoes as Becky has. How many shoes does Bobby have? Let x be the number of pairs of shoes that Becky owns. Since 13 pairs is 5 less than twice as many pairs as Becky owns, then the relationship is 2x-5=13. Adding 5 to each side of the equation, we get 2x=18. Solving for x, we get x=<<9=9>>9. Since Bobby has 3 times as many pairs of shoes as Becky has, then Becky has 3*9=<<3*9=27>>27 pairs of shoes. #### 27 My new house has 12 medium ceiling lights but I have seen small and large ceiling lights in other rooms. The small ones require 1 bulb, the medium ones require 2, and the large ones need 3 bulbs. How many bulbs should I buy if my wife says she saw twice as many large ceiling lights as medium ceiling lights and ten more small lights than medium ones? If the house has twice the number of large ones as medium ones then the house has 2*12 = <<2*12=24>>24 large ceiling lights Similarly, if it has 10 more small ones than the 12 medium ones then it has 10+12 = <<10+12=22>>22 small ceiling lights If one small ceiling light requires 1 bulb then 22 small ones will require 1*22 = <<1*22=22>>22 bulbs If one medium ceiling light requires 2 bulbs then 12 medium ones will require 2*12 = <<2*12=24>>24 bulbs If one large ceiling light requires 3 bulbs then 24 medium ones will require 3*24 = <<3*24=72>>72 bulbs Therefore the house will require 22 bulbs for the small ones + 24 bulbs for the medium ones + 72 bulbs for the large ones, for a total of 22+24+72=<<22+24+72=118>>118 #### 118 A plumber bought 10 meters of copper and 5 more meters of plastic pipe. If each meter cost $4, how much did the plumber spent on the copper and plastic pipe? He bought 10 + 5 = <<10+5=15>>15 meters of plastic pipe. The total meters of the copper and plastic pipe is 10 + 15 = <<10+15=25>>25. The plumber spent $4 x 25 = $<<4*25=100>>100 on copper and plastic pipe. #### 100
