Answer 6

i got $148.48

Answer 7

Yes, that's the cost of the materials. How many pounds of blended coffee did the grocer produce? The selling price is the cost/number of pounds

Answer 8

(realistically, you'd want to sell it for more than the cost!)

Answer 9

then divide by the total number of pounds
assuming you do not want to make a profit

Answer 10

okay so the total # of pounds would be 32 (10+12) so do i do 148.48/32? @whpalmer4 @satellite73

Answer 11

yes

Answer 12

You mixed 20 pounds and 12 pounds, so yes, divide by 32 pounds.

Answer 13

Answer 18

There's a book called "How to Solve Word Problems in Algebra" by Mildred Johnson which does a fine job of showing how to solve the dozen or so basic varieties of word problems. See if your library has a copy. Mixture problems (such as this one), rate problems, coin problems, all the usual favorites of the textbook authors attempting to make your life a misery :-)
