TO-DETERMINE: The number of batches of pasta that can be made.

Answer to Problem 32E
50 batches must be made for the cost to be equal in both cases.
Explanation of Solution
Given information: as provided in the question,
Cost of pasta machine is $33
Cost of ingredients to make 1 batch of pasta is $0.33
Cost of pasta at the store is $0.99
Calculation:
Assume the number of batches to be x
Therefore, the equation can be written as,
Batches of pasta to be made
Therefore, 50 batches must be made for the cost to be equal in both cases.
