Answer this question:Thirty-six marbles are divided between Mario and Manny in the ratio 4:5. If Manny decided to give 2 marbles to his brother, how many marbles does Manny have now?
The marbles are divided into 4 + 5 = 9 parts. Each part consists 36 / 9 = 4 marbles. So Manny had 5 parts x 4 = 20 marbles. After giving 2 marbles to his brother, he now has 20 - 2 = 18 marbles left.
The answer is 18.

Answer this question:Mr. Jesiah is a dairy cow farmer with cows producing 200 gallons of milk every day. The expenses for maintenance of the dairy farm and purchase of feeds is $3000 per month. Calculate his total income in June if he sells 1 gallon of milk at $3.55.
In a day, Mr. Jesiah's total income from the sale of the milk is $3.55 / gallon * 200 gallons / day = $710 / day. In June, his total income is $710 / day * 30 days = $21300. The net income from the sale is $21300 - $3000 = $18300.
The answer is 18300.

Answer this question:An animal shelter is having a pet adoption event where owners can adopt an animal for just the cost of the vet fees. Vet fees for dogs are $15, and vet fees for cats are $13. Eight families adopt dogs and three adopt cats. The vet donates a third of the fees they were paid for the adoption checkups back to the shelter. How many dollars did the vet donate?
The vet made 8 * 15 = $120 in dog vet fees. The vet made 3 * 13 = $39 in cat vet fees. The total vet fees were 120 + 39 = $159. The vet donated 1 / 3 of the fees, so they donated 159 / 3 = $53 back to the shelter.
The answer is 53.

Answer this question:Megan went to the store and bought a dozen eggs. When she got home, her neighbor gave her another dozen eggs from her chickens. Megan used 2 eggs to make an omelet for dinner and 4 eggs to bake a cake. When Megan's aunt came over for a visit, Megan gave her half of her remaining eggs. How many eggs per meal would Megan have if she plans to divide what she has left equally for her next 3 meals?
Megan has 12 + 12 = 24 eggs. After making her omelet and cake, she was left with 24 - 2 - 4 = 18 eggs. After giving half to her aunt, she was left with 18 / 2 = 9. Megan would have 9 / 3 = 3 eggs per meal for the next three meals.
The answer is 3.
