Question 837468
 


Let number of adults = a
 Let number of children = c
-------------------------------------------
 Total number of people: a + c = 210
 Total amount raised:   6a + 3.5c = $935.00
-------------------------------------------
1st.) From the information about the total number of people we can say:

a+c=210
a+c-c=210-c
a=210-c
-------------------------------------------
2.) Plug our "a" value we found in step 1) in the equation for the "total amount raised" to find how many adults and children were there.

Note: Total amount raised: 6a + 3.5c = $935.00

6(210-c) + 3.5c = $935.00

You said you just needed the set up so I'll let you finish it.
