Question 1097256: Nick is saving money for his college education. He invests some money at 9%, and $1400 less than that amount at 6%. The investments produced a total of $201 interest in 1 yr. How much did he invest at each rate. Answer by ikleyn(52787) (Show Source):
Let x be the money amount invested at 9%, in dollars.
Then the the money amount invested at 6% is (x-1400) dollars.
Then the total interest equation is
0.09*x + 0.06*(x-1400) = 201.
Solve for x.
