How many donors had type B blood? Round to the nearest person.

Answer
To find the number of donors with type B blood, we first need to determine what percentage of the total donors had type B blood. According to the table, 11% of donors had type B blood. The total number of donors is 145. To calculate the number of donors with type B blood, we use the formula: Number of donors with type B blood = (Percentage of type B blood / 100) * Total number of donors Substituting the values, we get: Number of donors with type B blood = (11 / 100) * 145 = 15.95 Since we need to round to the nearest person, we round 15.95 to 16. Therefore, the number of donors who had type B blood is 16.
