a salesperson earns $200 a week plus a 4% commission on her sales. which equation models the relationship between her sales in a given week, s, and her weekly earnings, e?\n$e = \\frac{200s + 4}{100}$\n$e = 200s + 4$\n$e = 4s + 200$\n$e = \\frac{4}{100}s + 200$
Answer
Explanation:
Step1: Identify fixed - and variable - part
The fixed weekly earning is $200. The variable part is 4% of sales. 4% can be written as $\frac{4}{100}$.
Step2: Form the equation
The weekly earnings $e$ is the sum of the fixed part and the variable part. The variable part is $\frac{4}{100}s$ (4% of sales $s$) and the fixed part is 200. So the equation is $e=\frac{4}{100}s + 200$.
Answer:
$e=\frac{4}{100}s + 200$ (the fourth option)
