Answer:
Well first you gotta fin the cost of 8 hats.
If one hat is equal to $7.50 then you multiply that by 8 to get $60.
So now you look at the graph and find out how many visitors is equal to 8 hats.
We know that 8 hats is equal to $60 and 1 visitor = $6
So divide 60 by 6 and you get 10
So 10 hats are equal to 8 hats.
Your answer is B) 10
Hope this is right .-.
