Adem is a coffee lover and he recently visited a new coffee shop. He ordered a large coffee with 15 ounces of coffee and 70 drops of cream. The barista asked him if he wanted to add any sugar, and Adem requested 15 packets of sugar. However, the barista only had 50 packets of sugar left, so she had to give Adem 3 packets of sugar for free. Now, Adem is wondering how much he has to pay for his coffee. Can you help him calculate the cost?
