Answer:
We conclude that 89 non-smoking places are required.
Step-by-step explanation:
We know that a new restaurant with 139 seats is being planned.
We know that 64% of the customers demand a smoke-free area.
We will use the following proportion, to calculate the number of non-smoking places.
[tex]139:100\%=x:64\%\\\\100x=139\cdot 64\\\\100x=8896\\\\x=88.96[/tex]
We conclude that 89 non-smoking places are required.
The number of seats that should be in the non-smoking area in order to be very sure of having enough seating there is 89.
Percentage can be described as a fraction of a number expressed as a number out of hundred.
In order to determine the number of seats that should be in the non-smoking area, multiply the percentage derived from the study by the total number of seats in the new restaurant.
Number of seats that should be in the non-smoking area = 64% x 139
0.64 x 139 = 88.96 seats
When rounded off to the nearest whole number, the seats become 89.
