Given:
Of 12 customers at one restaurant 10 said that they were very satisfied with the service.
Determine the number of satisfied customers out of 300 people.
Solution:
In order to determine the number of satisfied customers, we must take what percentage of 12 is 10. This can be done by dividing 10 by 12.
= 10/12
= 0.833
Since we are given a decimal answer, in order to convert it into percentage, we multiply the decimal by 100. Hence, in converting a percentage into decimal, we divide the percentage by 100.
= (0.833)(100)
= 83.3%
Now we know that 83.33% of the customers are satisfied, we can take the 83.33% of 300 to determine how many customers are satisfied. This can be done by multiplying 0.8333 with 300
= (0.8333)(300)
= 250 customers
Final answer:
= 250 customers
