Question

Someone please help!! Please!! It's number 21 and the graph at the right is what goes along with it

Answer 1

Sorry the picture was cut off

Answer 2

Forget the ham and the mayonnaise. They just want to know the number of combos of toppings.

So we're focusing on the set {lettuce, onions, peppers, olives}

Answer 3

that just involves us finding all the subsets of the set {lettuce, onions, peppers, olives}

Answer 4

there are 4 items in this set, so there are 2^4 = 16 subsets

that means there are 16 ways to order ham subs with mayonnaise (with any combo of those toppings or no toppings at all)

Answer 5

Wait why did we raise 2 to the fourth power?

Answer 6

the proof as to why/how it works is a bit complicated

but I'm using this idea
