The attendance at a baseball game was 400 people. Student Ticket cost $2 and adult tickets cost were $3. Total Ticket Sales were $1050. How many tickets of each type were sold?

This is what I did:

2x+400=1050

-400=-400

-----------

2x=650

x=325

3y+400=1050

-400=-400

-----------

3y=650

y=216.6=217

Two people told me its wrong...

One said to do this:

2x + 3(400-x)=1050

I don't really know how to break this down.

And, another person said:

If S is the number of students and A is the number of adults,

S + A = 400

2S + 3A =1050

2S + 2A = 800

Subtract the last equation from the one above. That will give you what A is. S is 400 -A

I don't really understand how the person got 800.

Is it like this?

2(S+A)=400

2S+SA=800

Is this right? If so, what do I do after this? I'm really confused. Help will be greatly appreciated.

S+A=400

A=400-S

2S+3(400-S)=1050

Solve for S

S=150

Plug back in top equation

A=250
