The people behind the drinks stall won’t see the stage…

The engineers have started setting up, and now that the

drink stand is in place, your buddies realize that it blocks

the view for whoever will be standing behind it.

Tom: Ugh. How many refunds?

Dave: I don’t know…we’d need to work out how many

people are in that area behind the screen.

Ben: Can’t we do something else? People are gonna be

so disappointed!

Chris: And it means less cash as well—which means

we’ll have less to split between us all!

Tom: I guess we could hire a giant screen maybe? But I

bet they are way expenisve.

Dave: But we’ll lose money if we give refunds

anyway—so anything less than that amount is worth it,

yes?

If you had to give refunds to all the people in that area, how much

would it cost you? (1 person per 2 square meters and $10 a ticket.)
