Answer 1

Answer: the sales for the month must be greater than or equal to $6666.7

Step-by-step explanation:

Let x represent her sales for the month.

Liz earns a salary of $2,500 per month, plus a commission of 6% of her sales. If she makes sales worth $s for the month, then her commission for the month would be

6/100 × s = 0.06 × s = 0.06s

Her total income for a month would be

2500 + 0.06s

She wants to earn at least $2,900 this month.

Therefore, the inequality that represents the situation would be

2500 + 0.06s ≥ 2900

0.06s ≥ 2900 - 2500

0.06s ≥ 400

s ≥ 400/0.06

s ≥ 6666.7
