Bakery Pastry Production Problem

A bakery specializes in making two types of pastries: croissants and muffins. The cost to produce one croissant is $1.50 and the cost to produce one muffin is $2.00. The bakery has a budget of $120 for the day. If all the croissants and muffins produced are sold at a profit margin of 40%, how many croissants can the bakery make if it decides to make 20 muffins?
