[Question]: 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?
[Answer]: 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.
So the answer is 35.

[Question]: Out of 480 employees, 10% got a salary increase while 20% got a travel allowance increase. How many employees did not get any increase?
[Answer]: 480 x 10 / 100 = 48 employees got a salary increase. 480 x 20 / 100 = 96 employees got a travel allowance increase. So a total of 48 + 96 = 144 employees got an increase. Therefore, 480 - 144 = 336 employees did not get any increase.
So the answer is 336.
