Question 101001: Bruce invested some money in the Thomas 300 fund and $3000 more than that amount in the Thomas 400 fune. For the year he was in the funds, the 300 fund paid 18% simple interest and the 400 fund paid 15% simple interest. If the income for the two investments totaled $3750 for one year, then how much did he invest in each fund.
Please advise...I don't even know where to begin.
