Martin owns a farm with hens. 10 hens do lay 80 eggs in 10 days. Martin decided to buy 15 more hens. How many eggs will all hens lay in 15 days?

How many eggs does 1 hen lay in 10 days? ** If 10 hens lay 80 eggs, then 1 hen lays 80 / 10 =

<<80/10=8>>8 eggs in 10 days. How many eggs does 1 hen lay in 5 days? ** That means one hen is laying 8 / 2 = <<8/2=4>>4 eggs in 5 days. How many eggs does 1 hen lay in 15 days? ** So in 15 days, 1 hen will lay 3 times more eggs, so 4 * 3 = 12 eggs. How many eggs will all hens lay in 15 days? ** All hens in total will then lay 25 * 12 = <<25*12=300>>300 eggs in 15 days. #### 300 Bella, Monica, and Rachel are friends who like jewelry. Bella has 10 earrings, which is 25% of Monica's earrings, and Monica has twice as many earrings as Rachel. How many earrings do all of the friends have? How many earrings does Bella have? ** Bellas has 100% / 25% = 4 times less earrings than Monica. How many earrings does Monica have? ** This means that Monica has 10 * 4 = <<10*4=40>>40 earrings. How many earrings does Rachel have? ** Rachel has two times fewer earrings than Monica, which means 40 / 2 = <<40/2=20>>20 earrings. How many earrings do all of the friends have? ** So all three friends, have a total of 10 + 40 + 20 = <<10+40+20=70>>70 earrings. #### 70 Seth lost 17.5 pounds. Jerome lost three times that many pounds and Veronica lost 1.5 pounds more than Seth. How many pounds did the 3 people lose in total? How many pounds did Seth lose? ** Seth = <<17.5=17.5>>17.5 pounds How many pounds did Jerome lose? ** Jerome = 3 * 17.5 = <<3*17.5=52.5>>52.5 pounds How many pounds did Veronica lose? ** Veronica = 17.5 + 1.5 = <<17.5+1.5=19>>19 pounds How many pounds did the 3 people lose in total? ** Total = 17.5 + 52.5 + 19 = <<17.5+52.5+19=89>>89 pounds How many pounds did the 3 people lose in total? ** The 3 people lost a total of 89 pounds. #### 89 Tommy ordered a total weight of 10 kilograms of apple, orange, grape, and strawberry fruits. He ordered 3 kilograms of apples, 1 kilogram of orange, and 3 kilograms of grapes. How many kilograms of strawberries did he order? How many kilograms of apples, oranges and grapes did Tommy order? ** Tommy ordered 3 + 3 + 1 = <<3+3+1=7>>7 kilograms of apples, oranges and grapes altogether. How many kilograms of strawberries did Tommy order? ** Therefore, Tommy ordered 10 - 7 = <<10-7=3>>3 kilograms of strawberries. #### 3 Mr Julien's store has 400 marbles remaining after the previous day's sales. Twenty customers came into the store, and each bought 15 marbles. How many marbles remain in the store? How many marbles did the 20 customers buy in total? ** If each of the 20 customers bought 15 marbles, then they bought 20*15 = <<20*15=300>>300 marbles in total from Mr Julien's store. How many marbles remain in the store? ** The number of marbles remaining in the store is 400-300 = <<400-300=100>>100 marbles #### 100 Ellie has 8 pairs of shoes. Riley has 3 fewer. How many pairs of shoes do they have in all? How many pairs of shoes does Riley have? ** Riley has 3 fewer pairs of shoes than Ellie’s 8, so 8 – 3 = <<8-3=5>>5 pairs of shoes. How many pairs of shoes do they have in all? ** Together, they have Ellie’s 8 + Riley’s 5 = <<8+5=13>>13 pairs of shoes. #### 13 Emery's family decides to travel for a weekend trip. They drive the first 100 miles in 1 hour. They stop at a McDonald's and then continue the rest of the journey for 300 miles. What's the total number of hours they traveled? How many hours did the next 300 miles take? ** If the first 100 miles took one hour, then let's say the next 300 miles took x hours. How many hours did the next 300 miles take? ** if 100 miles = 1 hour, then 300 miles =x. How many hours did the next 300 miles take? ** To find the number of hours traveled for the 300 miles, x = 300*1/100 How many hours did the next 300 miles take? ** x= <<3=3>>3 hours. How many hours did they travel? ** The total number of hours will be 3 +1 = <<3+1=4>>4 hours #### 4 Micah has 7 fish in his aquarium. Kenneth has three times as many fish in his aquarium and Matthias has 15 less fish than Kenneth in his aquarium. How many fish do the boys have in total? How many fish does Kenneth have? ** Kenneth has 7 x 3 = <<7*3=21>>21 fish in his aquarium. How many fish does Matthias have? ** Matthias has 21 - 15 = <<21-15=6>>6 fish in his aquarium. How many fish do the boys have in total? ** In total, the boys have 7 + 21 + 6 = <<7+21+6=34>>34 fish. #### 34 In a bookstore, a book costs $5. When Sheryll bought 10 books, she was given a discount of $0.5 each. How much did Sheryll pay in all?
