Problema Solution

Larry Mitchell invested part of his $11,000 advance at 3% annual simple interest and the rest at 2% annual simple interest. If his total yearly interest from both accounts was $280, find the amount invested at each rate.

Answer provided by our tutors

let


x = the amount invested at 3%

y = the amount invested at 2%


x + y = 11000


0.03x + 0.02y = 280


by solving the above system of equations we find


x = $6,000


y = $5,000
