Answer: She should budget $672.89 monthly next year for this service.
Step-by-step explanation:
Since we have given that
Amount he was able to save per month = $48.50
Total amount he spent for the year = $1254.89
Amount he saved for the year would be
[tex]48.50\times 12\\\\=\$582[/tex]
Amount left from total would be
[tex]1254.89-582\\\\=\$672.89[/tex]
Hence, She should budget $672.89 monthly next year for this service.
