Amy has saved $725 for a new guitar and lessons. Her guitar costs $475, and guitar lessons are $25 per hour. Determine how many hours of lessons she can afford.

First subtract the cost of the guitar: $725 - $475 = $250.

Divide the money left over by $25 to get how many hours of lessons she can afford: $250 : $25 = 10.

She has enough money left to pay for 10 lessons.

If you would like to know how many hours of lessons can Amy afford, you can calculate this using the following steps:

saved: $725

guitar costs: $475

guitar lessons: $25 per hour

$725 - $475 = $250 for guitar lessons

$250 / $25 = 10 hours of lessons

Result: Amy can afford 10 hours of guitar lessons.
