Question

There are 20,000 members of a zoo. The percent of
members having each membership type is shown in the
circle graph. How many members have a contributor
membership? What percentage of the noncontributory
memberships are individual memberships? Round to the
nearest percent.

Answer 1

1500 members have a contributor  membership.

64.8% of the noncontributory  memberships are individual memberships.

Step-by-step explanation:

There are 20,000 members of a zoo.

⇒ Total members = 20,000

From the graph shown,

7.5% of the members have a contributor  membership.

To find the number of members who have contributor  membership :

⇒ 7.5% of 20,000

⇒ (7.5/100) × 20,000

⇒ 7.5 × 200

⇒ 1500 members.

Therefore, 1500 members have a contributor  membership.

To find the percentage of the noncontributory  memberships are individual memberships :

The percentage of noncontributory  memberships = 100% - 7.5% ⇒ 92.5%

The percentage of individual memberships = 60%

∴ What percentage of the noncontributory  memberships are individual memberships ⇒ (60 / 92.5) × 100 = 64.8%
