If the interest rate on a savings account is 0.018%, approximately how much money do you need to keep in this account for 1 year
Diano4ka-milaya [45]
<span>We are not told how often the interest is compounded, so assuming it is <em /><u><em>compounded yearly</em></u>, you need to keep $9.99 in the account to pay the fee.

<u><em>Explanation: </em></u>
Compound interest follows the formula A=p(1+r)^t,
where:
A is the total amount in the account,
p is the amount of principal,
r is the interest rate as a decimal number,
and t is the number of years.

<u>For our problem: </u>
A = 9.99,
p is unknown,
r = 0.018% = 0.00018,
and t=1.

<u>This gives us: </u>
9.99=p(1+0.00018)^1;
9.99=p(1.00018).

<u>Divide both sides by 1.00018: </u>
9.99=p.</span>
