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

Answer 1

Answer:

b

Step-by-step explanation:

Answer 2

For this case we have:

Let:

• s: Profit from sales in a given week

• e: Seller's weekly profit

$e = 200 + c$

Where "c" represents the commission.

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

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

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

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

$c =\frac{4s}{100}$

Thus, e is given by:

$e = 200 +\frac{4s}{100}$

Answer:

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

$e = 200 +\frac{4s}{100}$
