Ruth is counting the number of spots on her cow. The cow has 16 spots on its left side and three times that number plus 7 on its right side. How many spots does it have total?

First multiply the number of spots on the left side by 3: 16 spots * 3 =

<<16*3=48>>48 spots Then add 7 to find the number of spots on the right side: 48 spots + 7 spots = <<48+7=55>>55 spots Then add the number of spots on each side to find the total number of spots: 55 spots + 16 spots = <<55+16=71>>71 spots #### 71 Matt orders 15 pounds of beef. He cuts that into 12-ounce steaks. How many steaks does he get? He buys 15*16=<<15*16=240>>240 ounces of steak That means he buys 240/12=<<240/12=20>>20 steaks #### 20 Jennifer will be 30 years old in ten years. At that time, her sister Jordana will be three times as old Jennifer. How old is Jennifer's sister now? When Jennifer is 30 years old in ten years, her sister Jordana will be 3*30=90 years old. She's currently 10 years younger, so she's 90 - 10 = 80 years old #### 80 Merry had 50 boxes of apples on Saturday and 25 boxes on Sunday. There were 10 apples in each box. If she sold a total of 720 apples on Saturday and Sunday, how many boxes of apples are left? Merry had a total of 50 + 25 = <<50+25=75>>75 boxes of apples. These 75 boxes is equal to 75 x 10 = <<75*10=750>>750 apples. There were 750 - 720 = <<750-720=30>>30 apples left. Thus, 30/10 = <<30/10=3>>3 boxes of apples are left. #### 3 A taco truck buys 100 pounds of beef. They use .25 pounds of beef per taco. If they sell each taco for $2 and each taco takes $1.5 to make how much profit did they make if they used all the beef? They made 100/.25=<<100/.25=400>>400 tacos Each taco gives a profit of 2-1.5=$<<2-1.5=.5>>.5 So they made a profit of 400*.5=$<<400*.5=200>>200 #### 200 A man owned 1/2 of a lot. He sold 1/10 of his share for the amount of $460. What is the worth of the entire lot? If 1/10 of the man's lot is equal to $460, then the man's land is worth $460 x 10 = $<<460*10=4600>>4600. Since 1/2 of the whole lot is worth $4600, then the whole lot is worth $4600 x 2 = $<<4600*2=9200>>9200. #### 9200 Sarah wants to start a cupcake business and was approved for a business loan. The loan has 0% interest if she pays the entire amount back in 5 years, which she decides to do. If she put $10,000 down as a down payment and her monthly payments are $600.00, how much was her loan for (including the down payment)? To avoid interest she'll make payments for 5 years. There are 12 months in 1 year so that's 5*12 = <<5*12=60>>60 months Each monthly payment is $600.00 and she'll pay that for 60 months for a total of 600*60 = $<<600*60=36000>>36,000 She also put $10,000 down as a down payment and her monthly payments came out to $36,000 so her loan was for 10000+36000 = $<<10000+36000=46000>>46,000 #### 46000 In five years, Grant will be 2/3 the age of the hospital that he is hired into. If Grant is currently 25 years old, how old is the hospital now? If Grant is currently 25 years old, he will be 25+5 = <<25+5=30>>30 years old in five years. If 2/3 represents Grant's age in five years, then the fraction representing the number of years the hospital is older than Grant is 1-2/3 = 1/3 If 2/3 represents 30 years, 3/3, which is the fraction representing the age of the hospital, represents 3/3*30*3/2 = 45 years. Currently, the hospital is 45-5 = <<45-5=40>>40 years old. #### 40 Adam has 18 magnets. He gave away a third of the magnets, and he still had half as many magnets as Peter. How many magnets does Peter have? Adam gave away 18/3 = <<18/3=6>>6 magnets. Adam had 18-6 = <<18-6=12>>12 magnets left. Peter has 12*2 = <<12*2=24>>24 magnets. #### 24 Rob planned on spending three hours reading in preparation for his literature exam. If he ends up spending only three-quarters of this time reading, and he reads a page every fifteen minutes, how many pages did he read in this time? 1 hour is 60 minutes so 3 hours is 3*60 = <<3*60=180>>180 minutes Three-quarters of 180 minutes is (3/4)*180 = <<(3/4)*180=135>>135 minutes He spends 15 minutes on 1 page so he will spend 135 minutes on 135/15 = <<135/15=9>>9 pages #### 9
