Answer :
Answer:
The number of tickets sold are
Children = 256
Adults = 486
senior citizen = 204
Step-by-step explanation:
let
x = children ticket = $10 per piece
y = adult ticket = $14 per piece
z = senior citizen = $6 per piece
x + y + z = 946 ( total tickets sold ) ---------- ( 1 )
Total receipt for performance
10x + 14y + 6z = $10588 --------------- ( 2 )
since the combined number of children and Adult tickets exceeded twice the number of senior citizen tickets by 334
x + y - 2z = 334 --------- ( 3 )
substract equation 3 from equation 1
3z = ( 946 - 334 ) = 612 therefore Z = 204
next we multiply equation (1) by 14
14x + 14y + 14z = 13244 ---------- ( 4 )
substract equation (2) from ( 4 )
4x + 8z = 2656
= 4x + 8(204) = 2656
= 4x = 2656 - 1632
therefore : x = 256
back to equation 1
256 + y + 204 = 946
y = 946 - ( 256 + 204 ) = 486
Hence the number of tickets sold are
Children = 256
Adults = 486
senior citizen = 204
