Question

Janice earns a 10% bonus based on her annual salary plus the number of sales she makes. She made 250 and earned a $5,000 bonus last year. Write and solve an equation to find her salary last year.

Answer 1

Let x be the annual salary.
Then 10% of x+250 equates 0.1(x+250).
Since the bonus equates $5000, then we get the equation:

`0.1(250+x)=5000,\text{ solving for x like this:}\\250+x= (5000)/(0.1)=50000,\text{ then}\\x=50000-250=49750`

The annual salary of Janice is 49750
