At his job, Tomas earns a commission plus an hourly wage. The function below describes the total dollar amount Tomas earns, based on the number of hours he works.

Question

f(h)=250+8.5h

Which of the following represents the hourly rate Tomas earns?

A.
250

B.
8.5

C.
f(h)

D.
h

Answer 1

The function \( f(h) = 250 + 8.5h \) describes Tomas's total earnings based on the number of hours \( h \) he works.

In this function:

• The term \( 250 \) represents a fixed amount (likely a base salary or commission).
• The term \( 8.5h \) represents the variable earnings based on the hourly wage, where \( 8.5 \) is the hourly rate.

Thus, the hourly rate Tomas earns is represented by the coefficient of \( h \).

The correct answer is:

B. 8.5
