Answer: [tex]f=30t+50[/tex]
Step-by-step explanation:
Given: Jabari's total fee, f, for a single job is a function of the number, t, of hours it takes him to complete the job.
For every job, he charges an initial fee plus $30 for each hour of work.
let m be his initial fee.
Then [tex]f=30t+m[/tex].......(1)
Also, his total fee for a 4-hour job, for instance, is $170.
Put t=4 and f=170 in (1), we get
[tex]170=30(4)+m\\\Rightarrow170=120=m\\\Rightarrow\ m=170-120\\\Rightarrow\ m=50[/tex]
Now, put m=50 in the (1), we get the function's formula for Jabari's total fee, f as
[tex]f=30t+50[/tex]
Answer:
The answer is f = 30t + 50
