Question 734396
an investor invested a total of $2300 in two mutual funds. one fund earned a 7% profit while the other earned a 2% profit. if the investors total profit was $66, how much was invested in each mutual fund?
--------
Quantity Equation: a + b = 2300 dollars
Profit Equation:  7a +2b = 6600 
--------
Multiply Quantity Eq through by 2:
2a + 2b = 2*2300
7a + 2b = 6600
-------------------
Subtract and solve for "a":
5a = 2000
a = $500.00 (amt invested at 7%
----
b = 2300-500 = $1800.00 (amt invested at 2%)
