7. In the school hallway, there is a machine with hot chocolate that costs 3 kuna. At the end of the month, 248 2-kuna coins, 189 1-kuna coins, 87 50-lipa coins, 45 20-lipa coins, and 35 10-lipa coins were taken out of it. How many cups of hot chocolate were sold in that month?
First method:

The total value of 2 kuna coins is $248 \cdot 2=496$ kuna, 1 POINT
the 1 kuna coin is $189 \cdot 1=189$ kuna, ..... 1 POINT
the 50 lipa coin is $87 \cdot 50=4350$ lipa, which is 43 kuna and 50 lipa, ..... 1 POINT
the 20 lipa coin is $45 \cdot 20=900$ lipa, which is 9 kuna, ..... 1 POINT
and the 10 lipa coin is $35 \cdot 10=350$ lipa, which is 3 kuna and 50 lipa. ..... 1 POINT
In total, this amounts to 741 kuna. ..... 3 POINTS
Since $741: 3=247$, 247 cups of chocolate have been sold. ..... 2 POINTS
