= 100*( 1.003^ 12+ 1.003^ 10+...+ 1.003)

= 100* 1.003*( 1.003^ 12- 1)/( 1.003- 1)

= 100.3*( 1.003^ 12- 1)/0.003

= 100300*( 1.003^ 12- 1)/3

= 100300*0.0366/3

= 1223.7 yuan

So little. The interest is too low.

I hope it helps you.

If you have any questions, you can ask them.

Thanks for adoption
