You can put this solution on YOUR website!
Ok so you have $485 to begin with.
So %24485+-+%24230+=+%24255 after paying for the bus.
Now %24225+-+%245%2A44+=+225+-+%24220+=+%245 This is the amount remaining after you pay admission for the students and teachers. 42 students plus 2 teachers gives you 44, and you multiply buy the cost per ticket which is $5.
Since tickets are $5 each you can only invite one guest.
An equation would be
5*G = the amount of money left after the bus + tickets
