Mac deposited $918.78 in a savings account that earns 2.1% simple interest. What is mac's account balance after 10 years?

Question

anonymous · Answer

initial = 918.78
interest= .021
time = 10 years
so equation is... initial*e^(time*interest)

anonymous · Answer

so it would be 918.78(10*0.021)?

anonymous · Answer

no, (10*.021) has to be to the power of e. and e is equal to 2.7818... or something, it should be on your graphing calculator.

anonymous · Answer

I don't have a graphing calculator. What would E be? I got the rest but I have no idea what e is.

anonymous · Answer

with out e I got 192.94.

I think it would be 918.78(10*0.021)=192.94+918.78= 1,111.72

if you multiply 10 by 0.021 it equals  0.21
