Taylor plans to use $2100 to open a savings account with an annual interest rate of 1.85%. How much more interest will he earn over 8 years if he chooses a compound interest account that compounds interest annually instead of a simple interest account? Round your answer to the nearest cent. simple interest: I = P • r • t interest compounded annually: A = P (1 + r)t $

OpenStudy (qwertty123):

Taylor will earn $21 more in compounded interest than in simple interest. Given: Principal = 2100 interest rate = 1.85% term = 8 years Simple Interest = Principal * interest rate * term = 2100 * 1.85% * 8 = ?

310.8

OpenStudy (qwertty123):

YES Compounded Interest = Principal * (1+r)^t = 2100 * 1.0185⁸ = 2100 * 1.158 =?

OpenStudy (thecuteone25):

2431.80

OpenStudy (qwertty123):

YES! Interest from Compounded Interest : 2431.80 - 2100 = 331.80 Simple Interest = 310.80 Compounded Interest = 331.80 331.80 - 310.80 = ? That is going to be your answer then! :)
