Answer:

585

Step-by-step explanation:

(800/312)= (1500/x)

solve for x

x= 585

585

the number of people is multiplied by 39% each time so to figure out how many people will participate out of 1500 you will multiply 39% by 1500 and to get 39% to a decimal , you divide by 100.

39% / 100 = 0.39

0.39 * 1500 = 585

hope this helps!
