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

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
