Philip is a painter. He makes 2 paintings per day. If he already has 20 paintings, how many paintings in total will he have after 30 days? Let's be accurate as possible.
The number of paintings Philip will make after 30 days is 2 paints / day * 30 days = 60 paintings. Then, the total number of his paintings will be 60 paintings + 20 paintings = 80 paintings.
The answer: 80.
