Asalesperson 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? a. e=200s+4/100 b. e = 200s + 4 c. e = 4s + 200 d. e=4/100s + 200

For this case we have:

Let:

Where "c" represents the commission.

The commission on sales can be observed with the application of a rule of three:

s ---------> 100%

c ---------> 4%

Thus, e is given by:

The equation that models the relationship between her sales in a given week, s, and her weekly earnings, e is:

Option d

it has the same slope and a different y-intercept

hope this : )
