Writing: A cafe sells a regular cup of coffee for $1 and a large cup for $1.50. Melissa and her friend buy 5 cups of coffee and spend a total of $6. Explain how to write and solve a system of equations to find the number of large cups of coffee they bought. Use the canvas to explain. You are not required to solve the system of questions, but your response should include the system and a narrative explaining how you set it up.
