How much money did you make if you sold 220 chocolate cookies at $1 per cookie and 70 vanilla cookies at $2 per cookie? Let's think first. Chain of thought:
You sold 220 chocolate cookies at $1 per cookie earning 220 x 1 = $220. You sold 70 vanilla cookies at $2 per cookie earning 70 x 2 = $140. In total you earned 220 + 140 = $360.
Therefore, the answer is 360.
