Liz earns a salary of $2,100 per month, plus a commission of 4% of her sales. she wants to earn at least $2,900 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.

Let S = the amount of sales.

She earns 4% of her sales, this would be written as 0.4S ( you multiply the percent as a decimal by the amount of sales).

You then need to add that amount to her salary so you now have 0.4s + 2100

She wants to earn at least 2900 so the inequality becomes:

2900 ≥ 0.4s + 2100

Her sales would need to be:

800 ≥0.4s

s≥ 800/0.4

s ≥ 2000

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
