Rosalinda invested some of her $15,000 in bonds that made a 6% profit and the rest in bonds that made a 10% profit. If the profit on the 10% bonds was $1,000 more than the profit on the 6% bonds, how much did Rosalinda invest in the 6% bonds
Let the amount of bonds @ 6%=B, then the balance,
15,000 - B=Bonds @ 10% interest
.10(15,000 - B) =.06B + 1,000
1,500 - .10B =.06B + 1,000
B=$3,125 Bonds at 6% interest rate.
$15,000 - $3,125 =$11,875 Bonds at 10% interest rate.
