a + c = 610, therefore c = 610 - a
3a + c = 1250
Substitute 610-a 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.

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