Question 41364: a grocer sold 450lb of ground beef in one day. Two grades of beef, regular at $1.20 per pound and lean at $1.40 per pound, wer sold. If the total sales were $592, how much of each type of ground beef were sold.
1.20x + 1.40(450-x)= 592
1.20x + 630 -1.40x= 592
-.20x + 630 = 592
630 - 592 =.20x
38=.20x
38/.20 = .20x/.20
ans.19

this one is practically solved, except for the mis-calculation.
38/.20=.20x/.20x
190=x
x lb is the amount of regular beef, and 450-x is the amount of lean beef sold.
regular=190 lb
lean=450 - 190= 260 lb
