The answer will be A.
p(x)=r(x) - c(x) Formula
p(x)=(12x) - (5x + 20) Substitution

p(x)=7x - 20 Combine like terms
That is your answer

Answer: (a)350 + 0.05x ≥ 600 (b) $5000
Explanation:
Fixed Salary = $350
Variable = 5% on sales
Let x the sales amount
Equation: 350 + 0.05x ≥ 600
350 + 0.05x ≥ 600
0.05x ≥ 600 - 350
0.05x ≥ 250
x ≥ $5000
