Question

Liz earns a salary of $2,000 per month, plus a commission of 8% of her sales. She wants to earn at least $2,500 this month. Enter an inequality to find amounts of sales that will meet her goal. Identify what your variable represents. Enter the commission rate as a decimal. What is the inequality that represents the situation.

Answer 1

Answer: $2000 + 0.08s ≥ $2500

Explanation:

The expression that will be used to calculate the earnings of Liz will be:

= b + (c × s)

Where:

b = base salary = $2,000

c = commission rate = 8% = 8/100 = 0.08

s = the sales that the commission rate will be applied against.

The inequality to find amounts of sales that will meet Liz goal will be:

= b + (c × s)

= $2000 + (0.08 × s) ≥ $2500

= $2000 + 0.08s ≥ $2500
