Explanation:
For each value in the table, you will divide it over 200 because there are 200 people total in this survey. Doing so will give you the decimal form of the percent. From here you move the decimal point over 2 spots to the right to get it to percent form.
For instance, in the top left corner we have 104 people satisfied with plan A. This is out of 200. So 104/200 = 0.52 = 52% are satisfied with plan A. We'll write 52% in the top left corner. The other cells of the table are filled in a similar fashion.
An alternative route is possible. Since we are given a limited amount of choices (rather than fill in the blank), we can note that 8 is the smallest value in the table. This must mean that it corresponds to the smallest percentage in the list of options. Sure enough 8/200 = 0.04 = 4%. Then we have 24 as the next smallest item in the original table. It corresponds to the next smallest percentage 12%, and sure enough 24/200 = 0.12 = 12%. This process can be continued until you fill out the table. Keep in mind that this method only works if you are given a list of choices like this. Otherwise, it is ideal to use a calculator to compute the percentages.
