Answer:
The number of parents tickets sold was 904
The number of teachers tickets sold was 563
The number of students tickets sold was 1,451
Step-by-step explanation:
Let
x ----> the number of parents tickets sold
y ----> the number of teachers tickets sold
z ----> the number of students tickets sold
we know that
y=563 ----> given value
z=y+888
substitute the value of y
z=563+888=1,451
x=904 ----> given value
x+y+z=904+563+1,451=2,918
therefore
The total tickets sold were 2,918
The number of parents tickets sold was 904
The number of teachers tickets sold was 563
The number of students tickets sold was 1,451
