Each land carrier takes 2000 pieces per load and each air carrier 1250 pieces per load the loading equipment is able to handle as many as 150 loads per day. let x be the number of loads by land, y the number of loads by air.

I know its B or D but which one is it?

A) 1250x+2000y>=180000 x+y>=150

B) 2000x+1250y<=180000 x+y<=150

C) 1250x+2000y<=180000 x+y<=150

D) 2000x+1250y>=180000 x+y>=150
