Please solve the inequality

Question

.04 x + .06(12000-x) >= 650

.04x + 720 - .06x ¡Ý 650
-.02x ¡Ý -70
x ¡Ý -70/-.02
x ¡Ý 3500

I think this is wrong and what is below is correct? Which is right? Thanks!

.04x + 720 - .06x ¡Ý 650
-.02x ¡Ü -70
x ¡Ü -70/-.02
x ¡Ü 3500

Answer 1

.04x + 720 - .06x ¡Ý 650
-.02x <= -70
x < = -70/-.02
x < = 3500

Or do the sign go the other way like this?

.04x + 720 - .06x ¡Ý 650
-.02x > = -70
x > = -70/-.02
x > = 3500

Which would be the solution to solve this inequality?

.04 x + .06(12000-x) >= 650
