One day a coffee shop sold 360 cups of coffee, some regular coffee and the rest decaffeinated. The shop sold 3 times as many cups of regular coffee as cups of decaffeinated coffee. The shop made 100 cups of regular coffee with foamed milk. How many cups of regular coffee did the shop make without foamed milk? Solve this problem in two ways: with the aid of a diagram and with algebraic equations. Explain both solution methods, and discuss how they are related
