Answer :
Answer:
Step-by-step explanation:
let x = adults and y = senior citizen
x + y = 323 equation 1
5x + 2y = 967 equation 2
multiply equation 1 by -5 to eliminate x
-5(x + y) = 323
-5x -5y = -1615 equation 3
add equation 2 and equation 3
5x + 2y = 967
-5x -5y = -1615
_____________
-3y = - 648
divide both sides by -3
y = 216
There are 216 senior citizens
323 - 216 = 107 adults
$5 x 107 = $ 535
$2 x 216 = $ 432
To check
$535 + $432 = $967
