Zach is planning to invest up to $50,000 in corporate and municipal bonds. The lest he will invest in corporate bonds is $6000 and he does not want to invest more than $27,000 in corporate bonds. He also does not want to invest more than $34,650 in municipal bonds. The interest is 8.5% on corporate bonds and 6.8% on municipal bonds. This is simple interest for one year. What is the maximum income?

solve using linear programming.

i already got that the equation is I=.085*27000+.068*23000, equals $3859, I just dont know how to graph these

maximize
.085 x + .068 y

x+y <= 50,000
x>=6,000
x<=27,000
y<=34,650
x+y>=1 phony to fill fields

I get $3859 at (27000, 23000)
