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 and think first.
96
Anna baked 4 x 20 = 80 cupcakes.

She sold 80 x 3 / 5 = 48 cupcakes.

Thus, she earned 48 x $2 = $96 from it.

.

So, the final answer is 96
