Darron uses a family recipe to make hamburgers. If he plans on using 1 1/3 cups of bread crumbs, about how many pounds of hambur
gers does Darron need to use to keep the relationship between bread crumbs and hamburgers proportional? Bread crumbs (c) 1/4 1/2 3/4
Hamburgers (lb) 1 2 3
In order to find the answer for this, we need to use proportions and cross multiply. Given that 3/4 of bread crumbs yields 3 hamburgers, and he plans on using 1 and 1/3 cup of bread crumbs, it will look like this: 3/4 over 3 : 4/3 over ?. So we cross multiply 3 by 4/3 and we get 4. Then divide 4 by 3/4 and we get 16/3 or 5 and 1/3. Therefore, the pounds of burgers that he needs to use is 5 and 1/3 pounds. Hope this helps.
Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).
Profit will be achieved when the money earned is greater than the money spent so, 336 + (n*12) = n*28 any subsequent units sold would result in profit 336 = 28n - 12n 336 = 16n => n = 336/16 = 21 21 units must be sold to draw even any more would result in profit
