so you can do this by using a system of equations
x=student tickets
y=adult tickets
x+y=394
x+56=y
then you substitute y in
x+(x+56)=394
2x+56=394
2x=394-56
2x=338
x=169 which is the number of student tickets
then you find the amount of adult tickets
x+56=y
169+56=y
225=y
and now you can check it
225+169=394
394=394
Answer:
169 student tickets were sold
225 adult tickets were sold
x=student tickets
y=adult tickets
x+y=394
x+56=y
then you substitute y in
x+(x+56)=394
2x+56=394
2x=394-56
2x=338
x=169 which is the number of student tickets
then you find the amount of adult tickets
x+56=y
169+56=y
225=y
and now you can check it
225+169=394
394=394
Answer:
169 student tickets were sold
225 adult tickets were sold
Let s be the number of student tickets.
Let a be the number of adult tickets.
s + a = 394
s = a - 56
Substitute a-56 in equation 1.
a - 56 + a = 394
2a - 56 = 394
2a = 450
a = 225 tickets
Let a be the number of adult tickets.
s + a = 394
s = a - 56
Substitute a-56 in equation 1.
a - 56 + a = 394
2a - 56 = 394
2a = 450
a = 225 tickets
