Is this rsm? lol okay.
x is the amount of money invested at 5%
y is the amount of money invested at 6%
the total amount of money invested is $6000, or x+y
when it says the yearly income is $337.50, it means that the 5% of x plus the 6% of y equals $337.50.
now write the two equations:
x+y =6000
0.05x + 0.06y = 337.50
now, find y for the first equations, which is y= 6000 - x. use this equation to substitute for the second equation.
0.05x + 0.06(6000 -x) = 337.50
blah, blah, blah, solve for x... you should get x = 2250, and y = 3750.
I hate money problems like this, hope it helps.
The answer in inequality form is t< -6.7
B=-3
because you divide 27 by -9 to get y by its self
