18. a or b (same thing). Because $1.25 is the MAXIMUM price, c will be less than $8 (the cooler) + $1.25n (price of n drinks).
17. d - 150 bands. 125 bands would not be enough to get $500. That would only make $375. With 150 bands you are getting $525, however it's better to have more than wanted!
16. You can work out that one ticket is $2. (20/10 is 2). Therefore she will get $400 by selling 200 tickets.
