Hello there. To solve this question, we'll have to set up an equation for each of the situations below.

a) The pay P for t hours at $17 an hour.

For this, we have a function P of t, that is, the pay depends on the number t of hours worked.

We can find the function by simply multiplying the pay for an hour by the number of hours, that is


P(t)=17t

This is the answer contained in the option C).

b) The total pay P for a day of t working hours on which you charge a base rate of $32 and $14 for each hour worked.

In this case, again we multiply the number of hours worked by the cost for each hour and add $32, therefore


P(t)=14t+32

This is the answer contained in the option A).

c) The total pay P for t hours at $22 and $16 for each additional hour.

In this case, we multiply 22 by the first hour, in this case, 1 and add it to 16 multiplied by (t - 1), that is, when t = 1, you get 0, that is, P = 22, therefore


P(t)=22+16\cdot(t-1)

This is the answer contained in the option D.
