 As a salesperson, you are paid $92 per week plus $4 per sale. This week you want your pay to be at least $200. Write an inequality for the number of sales you need to make, and describe the solutions.

A)92 - 4s ≤ 200; s ≤ 26
B)92 + 4s ≥ 200; s ≥ 26
C)92 - 4s ≤ 200; s ≤ 27
D)92 + 4s ≥ 200; s ≥ 27

The equation has to include the total pay that is greater than (≥) $200 AND the $4 per sale has to be added to the $92 weekly rate. The only option that is valid then is D) 92 +4s ≥ 200.

Let's solve for s:

92 + 4s ≥ 200
subtract 92 from both sides

4s ≥ 108
divide both sides by 4

s ≥ 27


ANSWER: D) 92 + 4s ≥ 200; s ≥ 27

Hope this helps! :)
