Alan counted how many chairs the office canteen has. It has 2 round tables and 2 rectangular tables. Each round table has 6 chairs, and each rectangular table has 7 chairs. How many chairs are there in all? Let's be accurate as possible.
The number of chairs at the round tables is 2 tables × 6 chairs / table = 12. The number of chairs at rectangular tables is 2 tables × 7 chairs / table = 14. There are 12 chairs + 14 chairs = 26 chairs in the canteen.
The answer: 26.
