Students sold 400 tickets for a playoff football game at school. some tickets are for students and costs 3.00. while the rest are adult tickets that costs 8.00.the total value of tickets sold was $1580.00
a. write a system of equations that represents this situation

b. solve this system of equations to determine how many of each type of ticket is sold.

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
-3s-3a=-1200  +
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

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
