Answer: Beth should make 7.5 batches of banana muffins.
Step-by-step explanation: Given that Beth made a batch of blueberry and banana muffins. Each batch is 6 muffins and she makes 2.5 batches of blueberry muffins.
We are to find the number of batches of banana muffins that Beth should make if she she wants to have a total of 60 muffins.
We have
1 batch = 6 muffins.
So, 2.5 batches = 6 × 2.5 = 15 muffins.
Let n represents the number of banana muffins that Beth should make.
Then, according to the given information, we have
[tex]15+n=60\\\\\Rightarrow n=60-15\\\\\Rightarrow n=45.[/tex]
Therefore, number of batches of banana muffins will be
[tex]\dfrac{45}{6}=7.5.[/tex]
Thus, Beth should make 7.5 batches of banana muffins.
