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 does d(4) = 37 mean?

• After 4 hours of work, Derek now makes $37 an hour instead of $9.25.

• Derek needs $4 more to have $37 total.

• After working 4 days, Derek makes $37 total.

• After 4 hours of work, Derek makes $37.
