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? Think carefully first, then make a decision:
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.
