###Human: Frank went to a shop to buy some food for his breakfast. He bought 10 buns for $0.1 each, two bottles of milk, for $2 each, and a carton of eggs, which was three times more expensive than one bottle of milk. How much did Frank pay for his breakfast shopping?, ### Assistant: For the buns, Frank paid 10 * 0.1 = $1.
He bought two bottles of milk, for $2 each, so he paid for them 2 * 2 = $4.
One carton of eggs was three times more expensive than one bottle of milk, so it cost 3 * 2 = $6.
So for all his shopping Frank had to pay 1 + 4 + 6 = $11. 
 So the answer is :  11
