Hi,
Let x be the number of bushels of the 1.50/bushel corn.  Then (140-x) would be the number of bushels for the 080/bushel corn
1.50 x +  .80(140-x) = 1.20*140
1.50x + .80*140 -.8x = 1.20*140
.7x = .4*140
x = 80 bushels of the 1.50/bushel corn
(140-x) = 60 bushels of the .80/bushel corn
check your answer
1.5*80 + .80*60 = 120 + 48  =168
