Answer:
144 meals for costumers and 12 for employees.
Explanation:
If Momoka prepared 156 meals, the major number of meals she prepared for costumers was 144, because if your divide 156 by 24 meals results 6.5, so the nearest number is 6, and 6(24)=144.
Now, if she prepared 144 for costumers, then she prepared only 12 for employees, because that's the difference 156-144=12.
Therefore, Momoka prepared 144 meals for costumers and 12 for employees.
