A cafe has 9 indoor tables and 11 outdoor tables. Each indoor table has 10 chairs, and each outdoor table has 3 chairs. How many chairs are there in all?
Thoughts? Step-by-step reasoning:
There are 9 indoor tables * 10 chairs = 90 chairs. There are 11 outdoor tables * 3 chairs = 33 chairs. The total number of chairs is 90 chairs + 33 chairs = 123 chairs.
Thus, the answer is 123.
