Question

Miley earns $10 per hour babysitting. Is the amount of money earned proportional to the number of hours she spends babysitting?

Answer 1

The amount of money she earns is proportional to the number of hours she babysits.  For every 1 hour she babysits, she earns $10.  If she babysits 2 hours, the pay is $20.  It is a $10 to 1 hour rate(ratio).
