Answer:
[tex]\boxed{\text{D. y $\geq$ 37 500 + 0.05x}}[/tex]
Step-by-step explanation:
y = Juan's income
$37 500 = his salary
x = his sales
0.05x = his commission on sales
$37 500 + 0.05x = his salary + commission
Juan's income must at least equal his salary + commission.
None of the options is correct, but the closest one is D.
[tex]\text{The condition is }\boxed{\mathbf{y \geq 37 500 + 0.05x}}[/tex]
