PLEASE HELP! I NEED TO FINISH THIS IN 5 MINUTES! A baseball park charges $5 for each adult ticket and $3 for each child ticket. Sunday, the park collected a total of $902 from 216 people. Let a represent the number of adult tickets sold and c represent the number of child tickets sold. Which system of equations can be used to find the number of adult and child tickets sold at the park on Sunday?

A. a + c = 902

5a + 3c = 216

B. a + c = 216

5a + 3c = 902

C. a + c = 216

5c + 3a = 902

D. a + 5a = 216

c + 3c = 902

B. a + c = 216

5a + 3c = 902

Step-by-step explanation: This is the correct answer, because a represents adults and c represents children, so a + c = 216 and 216 represents the total  number of people that the money was collected from. So, that would be correct for the first part of the system of equations. Next, 5a represents $5 for each adult, and 3c represents $3 for each child. While, 902 represents the total number of money collected at the park. Therefore the answer a + c = 216    5a+ 3c = 902 is the correct system of equations answer. Hope this helps ^-^.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
