Derek works at Subway making $9.25 an hour.  The function d(x)=9.25x tells us how much money Derek makes after x hours of working.  What is the meaning of d(4)=37?

• After 4 hours of work, Derek makes $37.
• Derek needs $4 more to have $37 total.
• After working for 4 days, Derek makes $37 total.
• After 4 hours of work, Derek now makes $37 an hour instead of $9.25.
