Given:
Fee cost for first month=$15 per month.
The objective is to find which of the given table matches the fee for next 5 months.
Since the fee for first month is given as $15. Then for the next 5months,
[tex]\begin{gathered} \text{Total f}ee=15\cdot5 \\ \text{Total f}ee=75 \end{gathered}[/tex]
By comparing the table, option A matches the fee structure.
Hence, (a) is the correct answer.
