Answer: her salary last year was $47500
Step-by-step explanation:
Let x represent her annual salary.
Janice earns a 10% bonus based oh her annual salary plus the number of sales she makes. It means that the expression for total bonus that she would earn from an annual salary of $x and sales worth $y would be
0.1x + y
She made 250 sales and earned a 5,000 bonus last year. The equation becomes
0.1x + 250 = 5000
0.1x = 5000 - 250
0.1x = 4750
x = 4750/0.1
x = $47500
