840 attendees

Step-by-step explanation:

Wholesome Pizza surveyed a random sample of 40 attendees about their favorite pizza.

Out of 40 attendees, 21 attendees said that sausage pizza was their favorite type of pizza.

First we calculate the percentage of  21 out of 40.

P = 21 ÷ 40 × 100 = 52.5%

52.5% attendees said that sausage pizza was their favorite type of pizza.

It is given that there are 1600 attendees, so we find out 52.5% of 1600.

× 1600

0.525 × 1600 = 840 attendees

In Trinity Food Festival 840 attendees said that their favorite type of pizza is sausage pizza.
