We have been given that Sam uses an industrial kitchen to bake several batches of his famous chocolate chip bars.
Further, we are given that Sam needs to weight out 78 ounces, plus or minus 2.5 ounces.
Therefore, the equation that can be used to find maximum or minimum amount, c, of chocolate chips that he can weight out is:
