Katarina is buying types of bird seed by the pound. For $11.00, she can buy 2 pounds of thistle seed and 1.5 pounds of sunflower seed. For $23.50, she can buy 3 pounds of thistly seed and 4 pounds of sunflower seed. How much does as pound of sunflower seed cost?

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.
