Problema Solution
a man invests money in two simple interest accounts. he invests twice as much in an account paying 11% as he does in an account paying 6%. if he earnes $91.00 in interest in one year from both accounts combined, how much did he invest altogether?
Answer provided by our tutors
let man invest $x at6% and $2x at 11%
0.06x + 0.11*2x = 91
0.28x = 91
x = 91/0.28 = 325
total investment = x+2x = 3x = 3*325 = $975
