Achef uses 3 3/4 pounds of semolina flour and 1 5/8 pound whole wheat flour for each batch of pasta she makes. one week she uses a total of 86 pounds of flour
how many batches does she make a week

It is to be noted that for this item, we more concern of the pounds of flour. The number of batches is calculated by dividing the total mass of flour used by the amount per batch. That is,
                                              n = 86 lbs / (1 + 5/8 lbs/batch)
                                              n = 52.92 batch
Thus, the chef makes approximately 53 batches of pasta.
