PsyDAG,
a + c = 610, therefore c = 610  a
3a + c = 1250
Substitute 610a for c in second equation and solve for a. Insert that value into the first equation and solve for c. Check by inserting both values into the second equation.

sam,
290 children 290X 1.00= 290
320 adults  320X 3.oo= 960
therefore 290+ 960= 1250
