In a bakery, a bag of bread rolls costs X dollars. A loaf of multigrain bread cost two dollars more then a bag of bread rolls. Mr. Lopez pays $50 for some multi grain loaves of bread. Write the number of loaves of bread he buys in terms of X

A bag of bread rolls costs x dollars

A loaf of multigrain bread cost two dollars more than a bag of bread rolls = x + 2

Let the number of loaves of multigrain loaves Mr Lopez bought be n, then

n (x + 2) = 50

n = 50 / (x + 2)

Therefore, the number of loaves of bread he buys is given by n = 50 / (x + 2).
