Gru is shopping with his minions again in the groceries store. Unfortunately, the store is closing soon and every item is going on sale discounted.
"How much does 15 bananas and 12 oranges cost?" Gru politely asks.
"That would be $9.30, Mr. Gru," replies the store manager.
"No no no... cheaper than before, cheaper than before, cheaper than before... more more more..." again the minions work their magic to get Gru to buy more.
"Alright alright! You minions. Never saw you so enthusiastic when you're working in the lab. How about 25 bananas and 15 oranges?" Gru gives in.
"That would be $13.50," the store manager says, with a big grin on his face.
