A hotel owner has determined that 83% of the hotel's guests eat eitherdinner or breakfast in the restaurant. Further investigation reveals that 30% of theguests eat dinner and 60% of the guests eat breakfast in the hotel restaurant. a) What proportion of the hotel guests eat both dinner and breakfast in the hotelrestaurant?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

only 10/60 isn't equivalent

hope this : )

answer: it's upside down and i can't read it
