The answer is D. y=500+0.25x
let's say y represents his total payment each week and x represents his total sales
x=$500
since he always gets 25% bonus of his total sales,
25%.500=0.25x
so, his total payment equals to
y = 500+0.25x
Answer:

Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to

we have
(-3,1) and (0,3)
substitute


step 2
Find the equation of the dashed line in slope intercept form

we have

---> given problem
substitute

step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so

see the attached figure to better understand the problem
