Hi, could anyone help me with this question?
I recently came across this question in one of my official mocks, however, with a slight change in statement 1.
Question
If $1,000 is deposited in a certain bank account and remains in the account along with any accumulated interest, the dollar amount of interest, I, earned by the deposit in the first n years is given by the formula I equals 1 comma 000 times open paren open paren 1 plus r over 100 close paren to the nth power negative 1 close paren, where r percent is the annual interest rate paid by the bank. Is the annual interest rate paid by the bank greater than 8 percent?
(1) The deposit earns a total of $210 in interest in the first few years.
(2) open paren 1 plus r over 100 close paren squared is greater than 1 period 15
Classic statement 1, when n=2, is sufficient, I understand, though when it says first few years, I am not sure. Could someone pls help?
