Some students want to buy pencils from a stationery shop. The price of one pencil is 20 cents. Tolu wants 3 pencils, Robert wants 5 pencils and Melissa wants 2 pencils. How much (in dollars) will the students spend altogether at the stationery shop? Let's think first. Chain of thought:
User
The three students want a total of 3 + 2 + 5 = 10 pencils. Each pencil cost 20 cents so 10 pencils cost 20 * 10 = 200 cents. 100 cents make a dollar so 200 cents make 200 / 100 = 2 dollars.
Therefore, the answer is 2.
