OpenStudy (calculusxy):

Sorry I meant h hours.

Can the equation be $300 - $8(h) ?

OpenStudy (anonymous):

yes, i believe that is correct

OpenStudy (calculusxy):

And on part B. Can you help me?

OpenStudy (anonymous):

OpenStudy (calculusxy):

Using the expression from Part A, calculate how much money the student needs to raise after working 30 hours. *is it $60?
