Which has the better deal? $56.00 over 25 gallons or $32.05 over 15 gallons?

!

The second one is the better price

Step-by-step explanation:

First of all, you have to find the unit rate of each. So, you divide dollars by gallon and for the first one you get 2.24 dollars per gallon and the second one you get 2.136667 so, obviously the second one is the ideal one because it have a lower unit rate

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.
