Answer: F (t) = 8 + 6t

Step-by-step explanation:

Hi to answer this question we have to write an equation analyzing the information given:

Initial fee: x Hours of work: t Price per hour: $6

So, if he earned $32 for a 4 hour job, the expression will be:

x + (6x4) = 32

Solving for x

x + 24 = 32

x = 32-24

x = 8

The initial fee is $8.

In conclusion, the function's formula for a fee for a single job F will be:

F (t) = 8 + 6t
