Conner has $25,000 in his bank account. Every month he spends $1,500. He does not add money to the account.

Write a linear model that shows how much money will be in the account after x months.

• y=25000x-1500

• y=25000+1500

• y=1500x+25000

• y=-1500x+25000

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.
