Question

A salesperson earns $350.25 per week plus 12% of her weekly sales. Which of the following describes the sales necessary for the salesperson to earn at least $800.50 in one week?

Answer 1

The equation for problem above is:
350.25+12/100*x=800.5
12/100*x=800.5-350.25
12/100*x=450.25
12x=45025
x=45025/12=3752.08

But the question is "at least" $800.50 so the final answer is


`x \geq 3752.08`
