Question

Leroi and Sylvia both put 100$ in a saving account. Leroi decides he will put in an additional 10$ each week. Sylvia decides to put in an additional 10% of the amount in each account each week. Who has more money after the second additional deposits

Answer 1

after the first week they will both put in 10 $, so they will have the same amount of money.

after the second week, Leroi will put in 10$,but Sylvia will put in 10% of what she already has there, 110 dollars, which means
`(10)/(100)*110= (1)/(10)*110=(1)/(1)*11`

So she will put in more money than Leroi: 11 dollars, and she has more money on the account!
