Answer:
7/4 or 1 3/4 cups of butter
Step-by-step explanation:
She makes a total of 3 + 4 batches of brownies on both days
So she makes 7 batches of brownies in total
For one batch, she uses 1/4 cups of butter
Since there are seven batches, to get the amount of butter she used, we'll simply multiply 1/4 by 7
this gives,
1/4 * 7
= 7/4
convert to a mixed fraction
1 3/4 cups of butter
