Question

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?

Answer 1

I'm guessing
\(\rm s=100\%\\c=4\%\)

\(c=\frac{4(s)}{100}\)

\(c=\frac{4s}{100}\)
Weekly earnings, e.
\(\it\ e=200+\frac{4s}{100}\)
