Answer:$6.21
Step-by-step explanation:
57.93 - (4 X 7.99)

$33.96 - $18.50
= $15.46
= $6.2088
=$6.21
The answer is option A.
The $50 initial membership fee represents the y-intercept (b), while the $20 monthly membership fee represents the slope (m) of the equation.
The answer to this is y = 3x - 2.
In the slope-intercept form y=mx+b, b is your y-intercept and in this problem, it will be -2. M is the slope which is 3.
