Answer 1

See below.

Explanation:

Please check the assumptions. I did not see a graph, so made assumptions in the calculations,

Given that for 10 guests, the total cost is $20, we can calculate a rate of $2/guest ( the unit rate). This seems too inexpensive, even for a hot dog and soft drink. But going on that, we can establish the relationship between x (the number of guests) and y (the total cost) as y = ($2/guest)*x.

The list of numbers does not provide a clear undertanding of what is being requested, The attached spreadheet calculates a number of guest options based on a rate of $2/guest. The area in green are the second list of values based on the numbers of guests.
