Algebra.Com's Answer #691334 by jorel1380(3719) You can put this solution on YOUR website! If Sarah is saving each week for 2 years,compounded weekly, then she makes a total of 104 payments, at .08/52, or 0.15385% interest each week. So: \n" ); document.write( "100000=P[(1+.0015385)^104-1]/.0015385 \n" ); document.write( "153.85=P(0.17337128198498002006399816563696) \n" ); document.write( "P=R 887.41 as the necessary amount of Sarah's weekly payment, in order to have an account balance of R100000 at the end of 2 years. ☺☺☺☺ \n" ); document.write( " |
