Answer:
16 batches is the answer.
Step-by-step explanation:
Amount of semolina flour used for 1 batch of pasta = [tex]\frac{15}{4}[/tex] pounds
Amount of wheat flour used for 1 batch of pasta = [tex]\frac{13}{8}[/tex] pounds
Total amount of flour used = [tex]\frac{15}{4}+ \frac{13}{8}[/tex]
= [tex]\frac{43}{8}[/tex] pounds
Let the number of batches made during the week be = b
A total of 86 pounds of flour is used in a week to make 'b' batches
b= [tex]\frac{86}{\frac{43}{8} }[/tex]
b = 16
Hence, a total of 16 batches are made in a week.
