Dany owns a farm, in his farm he has 4 cows and 3 sheep that eat 2 bushels a day. He also has 7 chickens that eat 3 bushels a day. How many bushels should he have to suffice the animals for a day?
Let's think: Dany has to have 4 x 2 = 8 bushels a day for the cows. He has to have 3 x 2 = 6 bushels a day for the sheep. And he also has to have 7 x 3 = 21 bushels a day for the chickens. Therefore, Dany has to have 8 + 6 + 21 = 35 bushels to suffice the animals for a day.. The answer is: 35.

Dilan, Martha, Phillip, and Veronica went to the park together to have some fun. They all had a different number of marbles: Dilan had 14 marbles, Martha had 20 marbles, Phillip had 19 marbles and finally, Veronica had only 7 marbles. They wanted to redistribute the marbles so they each had an equal number. How many marbles did each friend have at the end of the day?
Let's think: First find the total numbers of marbles: 14 + 20 + 19 + 7 = 60 marbles. After sharing them equally each person will get 60 marbles / 4 people = 15 marbles / person.. The answer is: 15.

Betty has 3 red beads for every 2 blue beads that she has. How many blue beads does Betty have if she has 30 red beads?

Roman the Tavernmaster has $20 worth of gold coins. He sells 3 gold coins to Dorothy. After she pays him, he has $12. How many gold coins does Roman have left?
Let's think:
Dorothy paid $12 for 3 gold coins so each gold coin is worth $12 / 3 = $4. The Tavern master originally had $20 worth of gold coins which is $20 / $4 = 5 gold coins. He gave 3 out of 5 gold coins to Dorothy so he now has 5 - 3 = 2 gold coins left.. The answer is: 2.
