So baically
reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought
400 tickest sold
total=400
a+s=400
value=rate times number of peple
student value=3s
adults value=8a
total value=1580
3s+8a=1580
a. system of equations area
s+a=400
3s+8a=1580
b. solve
s+a=400
3s+8a=1580
a+s=400
multiply by -3
-3s-3a=-1200
add to other eqaution
3s+8a=1580
<u>-3s-3a=-1200 +</u>
0s+5a=380
5a=380
divide 5
a=76
subsiute
s+a=400
s+76=400
subtract 76
s=324
a. s+a=400
3s+8a=1580
b. solution above
324 students
76 aduls
