[Question]: TreShaun's full marker has enough ink in it to paint three 4 inch by 4 inch squares. If he colors in two 6 inch by 2 inch rectangles, what percentage of ink is left?
[Answer]: Each 4 by 4 square equals 16 square inches because 4 x 4 = 16. Three squares equals 48 square inches because 3 x 16 = 48. Each rectangle uses 12 square inches because 2 x 6 = 12. Both rectangles will use 24 square inches because 2 x 12 = 24. He has 1 / 2 of the ink left because 24 / 48 = 1 / 2. He has 50% of the ink left because 1 / 2 x 100 = 50.
So the answer is 50.

[Question]: Megan’s grandma gave her $125 to start a savings account. She was able to increase the account by 25% from funds she earned babysitting. Then it decreased by 20% when she bought a new pair of shoes. Her final balance is what percentage of her starting balance?
[Answer]: Megan started with $125 and increased it by 25%, so $125 + (0.25)125 or $125 + $31.25 = $156.25. Then the balance decreased by 20%, so $156.25 – (0.20)156.25 or $156.25 - $31.25 = $125. $125 is the balance Megan started with, so her final balance is 100% of the starting balance.
So the answer is 100.

If Matthews has 60 cows, Aaron has 4 * 60 = 240 cows. Together, Aaron and Matthews have 240 + 60 = 300 cows. Since Marovich has 30 fewer cows than the combined number of cows that Aaron and Matthews have, Marovich has 300 - 30 = 270 cows. Altogether, the three have 270 + 300 = 570 cows.
So the answer is 570.
