c = 0.65n (option C)
Explanation:
4lbs of apple cost $2.60
1 lbs of apple =?
[tex]\begin{gathered} 1lbs\text{ of local fruit = }\frac{$2.60$}{4} \\ 1lbs\text{ of local fruit = 0.65} \end{gathered}[/tex]

the cost for n pounds of apples
c = cost per one × number of apples
c = $0.65 × n
c = 0.65n (option C)
