a) Difference in the weight of 3 bags of oregano and a bag of pepper.
We know that 3 bags of oregano would be: 3m
And for a bag of pepper would be n/2.
Then, the difference between them;
[tex](3m-\frac{n}{2})\text{ grams}[/tex]b) By the information given:
If m =200 and n=300.
[tex]\begin{gathered} \Delta w=3(200)-\frac{300}{2} \\ \Delta w=600-150 \\ \Delta w=450\text{ grams} \end{gathered}[/tex]
