Sonja makes her own peanut butter with peanuts and oil in a blender. She uses a ratio of two ounces of oil to smooth out every eight ounces of peanuts. Her last batch of peanut butter weighed 20 ounces. How many ounces of oil did she use?

Sonja uses 2 ounces of oil for 8 ounces of peanuts to make 2 + 8 = 10 ounces of peanut butter.

Her last batch weighed 20 ounces, so she made 20 / 10 =

<<20/10=2>>2 times her ratio. Thus, she used 2 * 2 = <<2*2=4>>4 ounces of oil. #### 4 On the first day of the journey, the Skipper sailed his ship halfway to the destination by traveling due east for 20 hours at a speed of 30 kilometers per hour, and then turned the ship's engines off to let them cool down. But while the engines were off, a wind storm blew his vessel backward in a westward direction. After the storm, the Skipper used his GPS device to determine the new location of the ship, and he discovered that he was only one-third of the way to his destination. How many kilometers had the ship been blown in a westward direction by the storm? Traveling 20 hours due east at 30 kilometers per hour, the ship sailed 20*30=<<20*30=600>>600 kilometers the first day. If half the distance to the destination is 600 kilometers, then 2*600=<<2*600=1200>>1200 kilometers is the total distance from start to destination. One-third of the distance from start to destination is 1/3 * 1200 = <<1200/3=400>>400 kilometers. Thus, the wind storm blew the ship in a westward direction for 600 - 400 = <<600-400=200>>200 kilometers. #### 200 Karen’s work tote bag is twice the weight of her husband Kevin’s briefcase when the briefcase is empty. When Kevin puts his laptop and work papers in his briefcase, it is twice the weight of Karen’s tote. Kevin’s work papers are a sixth of the weight of the contents of his full briefcase. If Karen’s tote weighs 8 pounds, how many more pounds does Kevin’s laptop weigh than Karen’s tote? Kevin’s full briefcase is 2 * 8 = <<2*8=16>>16 pounds. His empty briefcase is 8 / 2 = <<8/2=4>>4 pounds. The contents of his briefcase weigh 16 - 4 = <<16-4=12>>12 pounds. His work papers weigh 12 / 6 = <<12/6=2>>2 pounds. Thus, his laptop weighs 12 - 2 = <<12-2=10>>10 pounds. Therefore, Kevin’s laptop weighs 10 - 8 = <<10-8=2>>2 pounds more than Karen’s tote. #### 2 Tony paid $7 for 2 dozen apples and 1 bunch of bananas. Arnold paid $5 for 1 dozen apples and 1 bunch of bananas. How much does a bunch of bananas cost? Tony paid $7-$5= $<<7-5=2>>2 more than Arnold We know he bought the same number of bananas as Arnold but that he bought 2-1=1 dozen apples more than Arnold Therefore a dozen apples should cost $2 If Arnold paid $5 and $2 for a dozen apples then the bunch of bananas cost $5-$2=$<<5-2=3>>3 #### 3 If Stu has 9 books and Albert has 4 times as many books as Stu, how many books do Stu and Albert have in total? Albert has 4 * 9 books belonging to Stu = <<4*9=36>>36 books. So the pair have a combined total of 36 books belonging to Albert + 9 books belonging to Stu = <<36+9=45>>45 books. #### 45 In a race, there are eight runners. The first five runners finish the race in 8 hours, while the rest of the runners finish the race 2 hours later. Calculate the total time the eight runners took to finish the race. The first five runners took a combined total of 5*8 = <<5*8=40>>40 hours to finish the race. The number of runners who finished the race 2 hours later after the first five is 8-5 = <<8-5=3>>3 The 3 runners who finished the race 2 hours later took a total of 8+2 =<<8+2=10>>10 hours to run the race. Together, the three runners who finished the race in 10 hours took a total of 10*3 = <<10*3=30>>30 hours. All eight runners took 30+40 = 70 hours altogether to finish the race. #### 70 Keaton climbed a 30 feet ladder twenty times while working at the construction site. Reece, also working at the same site, climbed a ladder 4 feet shorter than Keaton's ladder 15 times. What's the total length of the ladders that both workers climbed in inches? If Keaton climbed his ladder twenty times, he covered a length of 30*20 = <<30*20=600>>600 feet. Reece's ladder, 4 feet shorter than Keaton's ladder, was 30-4 = <<30-4=26>>26 feet long. If Reece climbed the ladder 15 times, he covered a length of 15*26 = <<15*26=390>>390 feet. Keaton and Reece's total length covered while climbing the ladders is 390+600 = <<390+600=990>>990 feet. Since one foot is equal to 12 inches, the total length they climbed the ladders in inches is 12*990 = <<12*990=11880>>11880 inches. #### 11880 Emily makes $1,000,000 per year. If she has 10 employees who make $20,000 per year, how much would her salary be if she took part of her salary to make sure all of her employees make $35,000 per year. Each employee needs $35,000-$20,000=$<<35000-20000=15000>>15,000 more per year. In total, Emily needs to pay $15,000*10=$<<15000*10=150000>>150,000 extra. Emily will need to have a new salary of $1,000,000-$150,000=$<<1000000-150000=850000>>850,000 per year. #### 850,000 Linda bought two coloring books at $4 each, 4 packs of peanuts at $1.50 each pack, and one stuffed animal. She gave the cashier $25 and got no change. How much does a stuffed animal cost? The two coloring books amount to 2 x $4 = $<<2*4=8>>8. The 4 packs of peanuts amount to 4 x $1.50 = $<<4*1.5=6>>6. The total cost for the coloring books and peanuts is $8 + $6 = $<<8+6=14>>14. Thus, the stuffed animal cost $25 - $14 = $<<25-14=11>>11. #### 11 Monika went out for the day and spent some money. She went to the mall and spent $250. Then, she went to the movies and watched 3 movies back to back that each cost $24. Then she stopped by the farmer's market on her way home and got 20 bags of beans at $1.25/bag. How much money did Monika spend throughout her day? Monika spent 24*3 = <<24*3=72>>72 dollars at the movies. Monika spent 20*1.25 = <<20*1.25=25>>25 dollars at the farmers market. Throughout her day, Monika spent 250+72+25 = <<250+72+25=347>>347 dollars. #### 347
