Every time Mary bakes a batch of brownies, she uses 1/5 cup of chocolate. If she has 8/10 cup(s) of chocolate remaining, how many batches of brownies can Mary make? Input your answer as a whole number. giving 35 points if u answer.

Step-by-step explanation:

Number of cups of chocolate is directly proportional to the number of batches of brownies.

1/5 cups of chocolate = 1 batch of brownies

=> 8/10 cups of chocolate = (8/10) / (1/5)

= 4 batches of brownies.

Hence Mary can make 4 more batches.
