A two-way frequency table is shown below that displays the relationship between pizza type and pizza crust choices. We took a sample of 110 people and recorded the following results:

                        Thin Crust  Thick Crust   Stuffed Crust   Total

Cheese Pizza        3                 9               13                    25

All-Meat Pizza       5                15             25                     45

Hawaiian Pizza     2                 6              32                     40

Total                     10               30             70                    110


The restaurant is about to prepare pizza for a children's birthday party. Knowing that the party planner only wants cheese pizza, what percentage (rounded to the nearest whole percent) of the order will be for stuffed-crust pizza? 

52%

12%

Applying the sample data.....25   wanted cheese pizza...of these....13 wanted stuffed crust....so

 

13  / 25  =      52  / 100    =    52%
