Answer:
Step-by-step explanation:
s=3a
t=s+a
t=516
now lets use 3a instead of s.
516=3a+a
516=4a
a=129 (adult)
s=3(129)
s=387 (student)
The number of adult tickets sold is 129 if a total of 516 tickets were sold for the school day.
What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
The complete question is:
A total of 516 tickets were sold for the school day. There were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets were sold?
How many adult tickets were sold?
We have:
A total of 516 tickets were sold for the school day. There were either adult tickets or student tickets.
Let S be the number of tickets and A be the number of adults tickets
S = 3A
Total = S +A = 516
516 = 3A + A
A = 129
S =387
Thus, the number of adult tickets sold is 129 if a total of 516 tickets were sold for the school day.
