Question

a) 80
b) 90
c) 100
d) 120

Answer 1

The total number of attendees at the Perkins family reunion is 120.

Step-by-step explanation:

To find the total number of attendees at the Perkins family reunion, we can use the given information that 15% of the attendees are under twenty years old. We are also given that there are 18 attendees under twenty.

We can set up a proportion to solve for the total number of attendees:

15/100 = 18/x

Cross-multiplying, we get:

15x = 100 * 18

15x = 1800

Dividing both sides by 15, we find that x = 120.

Therefore, the total number of attendees at the Perkins family reunion is 120.
