Who has more money after the first additional deposit? Explain.

Who has more money after the second additional deposit? Explain.

Answers

Leroi’s account

$100
After first deposit = $100+$10=$110
After second deposit= $110 + $10 = $120

Sylvia’s account

$100
10% of $100 is $10
After first deposit = $100+ $10 = $110
10% of $110 = $11
After second deposit = $110 + $11 = $121

Therefore after their first deposit, both will have the same value in their accounts.
But after the second deposit, Sylvia will have 1$ more in her account than Leroi.
