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?
Step-by-step reasoning process below:
100
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.

.

Thus, the answer is 100
