Question

When hired at a new job selling jewelry, you are given two pay options:

Option A: Base salary of $15,000 a year, with a commission of 8% of your sales

Option B: Base salary of $22,000 a year, with a commission of 3% of your sales

In order for option A to produce a larger income, you would need sell at least $   of jewelry each year.

Answer 1

Let x = annual revenue (in $) from jewelry sales

We want 15000 + 0.08x > 22000 + 0.03x

Solve for x.
