Question

1. the linear equation representing a company charging a $15 service fee plus $30 per hour of work is:

a. $y = 15x - 30$
b. $y = 15x + 30$
c. $y = 30x + 15$
d. $y = 30x - 15$

Explanation:

Step1: Define linear equation structure

Linear cost equation: $y = mx + b$, where $m$ = hourly rate, $b$ = fixed fee.

Step2: Assign values to variables

$m = 30$, $b = 15$

Step3: Substitute into equation

$y = 30x + 15$

Answer:

c. $y = 30x + 15$
