Anumeha is mowing lawns for a summer job. for every mowing job, she charges an initial fee of $10 plus a constant fee for each hour of work. her fee for a 5-hour job, for instance, is $35.
let f(t) denote anumeha's fee for a single job f (measured in dollars) as a function of the number of hours "t" it took her to complete it.
write the function's formula.

Step-by-step explanation:

We know that Anumeha charges an initial fee of $10, this is an initial condition which represents the independent term in the function.

Then, she charges $35 for 5 hours, this means that the ratio of change is

That is, she charges $7 per hour. Now, let's call the hours, the given problem is modelled with the following expression

Therefore, the function's formula is
