The fixed fee touse the studio is $150 and the total cost charged for 2 hours is $300. Write anequation for P, in terms of t, representing the amount of money Sarah would have topay to use the studio for t hours.

Answer 1

Fixed fee is 150

Total cost for 2 hours is 300

If the fixed fee is 150, and Sarah paid 300, then she paid 150 for the fixed fee and anohter 150 for the two hours, that means that each hour is 75

Then we can write the equation:

P = 75t + 150

Answer:

P = 75t + 150
