If someone could help me get through this problem that would be great. This is actually college finite mathematics. I wasn't sure which thread to post this at. Thank You,

Minimize Z=30x1 + 15x2 + 16x3, subject to

5x1 + 3x2 + 4x3 (is greater than or equal to) 45

5x1 + 6x2 + 8x3 (is less than or equal to) 120

20x1 + 6x2 + 14x3 = 300

x1 (is greater than or equal to) 0, X2 (is greater than or equal to) 0, x3 (is greater than or equal to) 0

All of the numbers after an "x" are subscripts. I wasn't sure how to type subscripts. I also wasn't sure how to type "greater or equal to" so I just typed it out. Sorry. Thank You in advance for help on this problem
