Best ResponseYou've already chosen the best response.1Betty would like to prepare a meal using some combination of these three foods. She would like the meal to contain 15g of protein, 25g of carbohydrate, and 3g of fat. How many units of each food should she use so that the meal will contain the desired amounts of protein, carbohydrate, and fat?

Best ResponseYou've already chosen the best response.1I can't seem to remember how to approach this. I think it has something to do with linear transformation. hmm

Best ResponseYou've already chosen the best response.1Yah I might have to resort to that. These matrices are really confusing me. Maybe I'll just rewrite it as a system of equations and figure it out that way. :p

Best ResponseYou've already chosen the best response.1\[\large 15x_1+35x_2+25x_3=15\]\[\large 45x_1+30x_2+50x_3=25\]\[\large 6x_1+4x_2+x^3=3\] Oh ok I think I'm understanding.. Maybe I'm just suppose to treat this as an augmented matrix, and then I can throw it into my calculator. \[\large \left(\begin{array}{cccc}15&35&25&15\\45&30&50&25\\6&4&1&3\end{array}\right)\]
