Question

Chris can be paid in one of two ways. Plan A is a salary of ​$320 per​ month, plus a commission of 8​% of gross sales. Plan B is a salary of ​$715 per​ month, plus a commission of 3​% of gross sales. For what amount of gross sales should Chris select plan​ A?

Answer 1

The answer is: Chris should select Plan A if his total sales ≥ $7,900

Step-by-step explanation:

Plan A = $320 + 8%s

Plan B = $715 + 3%s

where s = gross sales

To find at what point should Chris choose Plan A, we must solve the equations given that Plan A = Plan B

$320 + 8%s = $715 + 3%s

8%s - 3%s = $715 - $320

5%s = $395

s = $395 / 5% = $7,900
