Granger went to the grocery store. He saw that the Spam is $3 per can, the peanut butter is $5 per jar, and the bread is $2 per loaf. If he bought 12 cans of spam, 3 jars of peanut butter, and 4 loaves of bread, how much is the total amount he paid?

The 12 cans of Spam costs $3 x 12 = $

<<3*12=36>>36. The total amount of 3 jars of peanut butter is $5 x 3 = $<<5*3=15>>15. And the total amount of the 4 loaves of bread is $2 x 4 = $<<2*4=8>>8. Therefore the total amount he will have to pay is $36 + $15 + $8 = $<<36+15+8=59>>59. #### 59 On Monday, Sydney sends 5 texts each to Allison and Brittney. On Tuesday, she sends 15 texts to each of them. In total, how many texts did Sydney send to Allison and Brittney on both days? Sydney sends 5*2=<<5*2=10>>10 texts on Monday. Sydney sends 15*2=<<15*2=30>>30 texts on Tuesday. In total, Sydney sends 10+30=<<10+30=40>>40 texts on both days. #### 40 John has a very inefficient toilet that uses 5 gallons of water per flush and his household flushed 15 times per day. He replaced it with a toilet that uses 80% less water per flush. How much water did John save in June? He used to use 5*15=<<5*15=75>>75 gallons of water per day. This means he used 75*30=<<75*30=2250>>2250 gallons a month. His new toilet uses 5*.8=<<5*.8=4>>4 gallons less water per flush. So, it only uses 5-4=<<5-4=1>>1 gallon per flush. That means he uses 1*15=<<1*15=15>>15 gallons per day. All in all, it accounts for a total usage of 15*30=<<15*30=450>>450 gallons. So, he saved 2250-450=<<2250-450=1800>>1800 gallons per month. #### 1800 A farmer is growing corn. For every 4 seeds he plants, he gets one ear of corn, that he can sell for $.1. It costs $.5 for a bag with 100 seeds. If he makes $40 in profit, how many ears did he sell? A single seed costs $.005 because .5 / 100 = <<.5/100=.005>>.005 It costs $.02 cents to grow an ear of corn because .005 x 4 = <<.005*4=.02>>.02 On each ear of corn he makes $.098 profit because .1 - .02 = .08 He sold 500 ears because 40 / .08 = <<40/.08=500>>500 #### 500 There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm? First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = <<2+1=3>>3 weeks Then multiply that number by the number of days per week: 3 weeks * 7 days/week = 21 days Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish/day = <<21*2=42>>42 fish Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = <<60+8=68>>68 fish Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = <<68-42=26>>26 fish #### 26 A cake of 400 grams is divided into eight equal parts. Nathalie eats one-eighth of the cake, and Pierre eats double what Nathalie ate. How much did Pierre eat, in grams? Nathalie ate 1/8 * 400g = <<1/8*400=50>>50g of cake. Pierre eats 2 * 50g = <<2*50=100>>100g of cake. #### 100 If you take the fastest speed of a rabbit and double it, add 4 to that then double it again you get 188. How fast is the rabbit? You doubled a number to get 188 so in reverse, you would divide by 2 so 188/2 = <<188/2=94>>94 You added 4 to this number and in reverse, you would subtract by 4 so 94-4= <<94-4=90>>90 You doubled a number to get 90 so in reverse you would divide by 2 so 90/2 = <<90/2=45>>45 is the fastest speed #### 45 The minimum age required to be employed at a company is 25 years. Dara aspires to work for the company and will be half the age of Jane in six years. If Jane is currently working for the company and is 28 years old, how long is it before Dara reaches the minimum age required by the company to be employed? In six years, Jane will be 28+6 = <<28+6=34>>34 years old. Dara will be half the age of Jane in six years, meaning she will be 34/2 = <<34/2=17>>17 years old in six years. Currently, Dara is 17-6 = <<17-6=11>>11 years old. Dara has to wait for 25-11 = <<25-11=14>>14 more years to reach the company's minimum age of employment. #### 14 On Tuesday, Mike had 45 books and Corey had twice as many books as Mike. On Wednesday, Mike gave 10 books to Lily, and Corey gave Lily 15 more than Mike gave. How many books did Lily get? Corey gave Lily 10+15 = <<10+15=25>>25 books to Lily. Lily got 25+10 = <<25+10=35>>35 books. #### 35 Four kids can wash three whiteboards in 20 minutes. How long would it take, in minutes, for one kid to wash six whiteboards? One kid can wash three whiteboards in 20*4=<<20*4=80>>80 minutes. One kid can wash six whiteboards in 80*(6/3)=160 minutes. #### 160
