Mr. Salazar had seven dozen oranges. He reserved 1/4 of it for his friend and was able to sell 3/7 of the remaining yesterday. Today, he saw four rotten oranges. How many oranges are left to be sold today?

Mr. Salazar had 7 x 12 =

<<7*12=84>>84 oranges. He reserved 84 x 1/4 = <<84*1/4=21>>21 oranges for his friend. Ha had 84 - 21 = <<84-21=63>>63 oranges to be sold yesterday. But only 63 x 3/7 = <<63*3/7=27>>27 oranges were sold yesterday. So, he had 63 - 27 = <<63-27=36>>36 oranges left. Since four oranges are rotten, then only 36 - 4 = <<36-4=32>>32 oranges are left to be sold today. #### 32 The price of a monster box of cereal is reduced by $24 after an oversupply in the market. If the initial price was $104, and Romina bought 20 of such boxes, calculate the total price she paid. If the initial price was $104, and the price of the monster box of cereal reduced by $24, the new price is $104-$24 = $<<104-24=80>>80 If Romina bought 20 such boxes, he paid 20*$80 = $<<20*80=1600>>1600 #### 1600 The students at Evelyn's school are keeping journals. They have 3 journal-writing sessions per week. Each student writes 4 pages in each session. How many journal pages will each student write in 6 weeks? In a week, a student writes 3*4=<<3*4=12>>12 pages. So in 6 weeks, each student will write 12*6=<<12*6=72>>72 pages. #### 72 Nicky is trading baseball cards with Jill. If Nicky trades two cards worth $8 each for 1 card worth $21, how many dollars of profit does he make? First find the total cost of the two $8 cards: $8/card * 2 cards = $<<8*2=16>>16 Then subtract the cost of the cards Nicky gave away from the cost of the card he received to find his profit: $21 - $16 = $<<21-16=5>>5 #### 5 At a pool party, there are 4 pizzas cut into 12 slices each. If the guests eat 39 slices, how many slices are left? There’s a total of 4 x 12 = <<4*12=48>>48 slices. After the guests eat, there are 48 - 39 = <<48-39=9>>9 pieces. #### 9 Paul goes fishing every Saturday. Last week he was able to catch 5 fish for every 2 hours he was fishing. How many fish did he catch when he was fishing for 12 hours? Paul caught 5 fish 12 / 2 = 6 times that day. So he was able to catch in total 6 * 5 = <<6*5=30>>30 fish. #### 30 If Jim has 20 apples, and Jane has 60 apples, and Jerry has 40 apples, how many times can Jim's number of apples fit into the average amount of apples for a person in the group? First, we need to find the average number of apples per person. We start by adding the three totals together, getting 20+60+40=<<20+60+40=120>>120 apples To finish finding the average number, we perform 120/3= <<120/3=40>>40 apples per person. Since Jim has 20 apples, we divide the average of 40 by Jim's total to find 40/20=<<40/20=2>>2 times that Jim's amount can fit into the average. #### 2 When three friends sold their video games, Ryan, the first of the three friends, received $50 more than Jason from his sales. Jason received 30% more money than Zachary from selling his video games. If Zachary sold 40 games at $5 each, calculate the total amount of money the three friends received together from the sale of the video games. The total amount of money that Zachary received from selling his video games is $40*5 = $<<40*5=200>>200 Jason received 30/100*$200 = $<<30/100*200=60>>60 more than the amount Zachary received after selling his games. The total amount of money that Jason received is $60+$200 = $<<60+200=260>>260 Together, Zachary and Jason received $260+$200 = $<<260+200=460>>460 from the sale of their video games. Ryan received $260+$50=$<<260+50=310>>310 from the sale of his video games. The three friends made a total of $310+$460 = $<<310+460=770>>770 from the sale of the video games. #### 770 Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm? Twice the number of pigs is 10 x 2 = <<10*2=20>>20. So, Hannah's family has 20 - 3 = <<20-3=17>>17 cows. They also have 17 + 6 = <<17+6=23>>23 goats. So, they have a total of 10 + 17 + 23 = <<10+17+23=50>>50 animals on their farm. #### 50 Beatrice is shopping for a new TV. First she looks at 8 TVs at one store in person. Then she looks at three times as many TVs at an online store. She looks at more TVs on an auction site online. If Beatrice looked at 42 TVs in all, how many did look at on the auction site? Beatrice looked at 3 x 8 TVs at an online store = <<3*8=24>>24 TVs. She looked at 8 TVs in person + 24 TVs online = <<8+24=32>>32 TVs. Beatrice looked at 42 TVs in all - the 32 she looked at = <<42-32=10>>10 TVs she looked at on an auction site. #### 10
