Anna used four baking trays to bake cupcakes. Each tray has 20 cupcakes and each cupcake was then sold for $2. If only 3/5 of the cupcakes were sold and the rest were kept, how much did Anna earn from it? Let's be accurate as possible.
Anna baked 4 x 20 = 80 cupcakes. She sold 80 x 3 / 5 = 48 cupcakes. Thus, she earned 48 x $2 = $96 from it.
The answer: 96.
