Alessandro Odom · Answer 1

The amount of interest that is incurred by depositing a certain amount is calculated through the equation,

I = P x r

where I is the interest, P is the principal, and r is the decimal equivalent of the given rate. Substituting the known values,

10 = P x (0.03/100)

The value of P from the equation is 33,333.33. Thus, an amount of $33,333.33 should be deposit to earn $10.
