Step-by-step explanation:
Week one and two
4 x 25 x 2
100 x 2
= 200
Week three
5 x 25 = 125
125+100
=225
Answer:
![x = \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Step-by-step explanation:
We want to solve for x in the equation in
![x + 4 = 5x + 2](https://tex.z-dn.net/?f=x%20%2B%204%20%3D%205x%20%2B%202)
Let us group like terms to obtain:
![4 - 2 = 5x - x](https://tex.z-dn.net/?f=4%20-%202%20%3D%205x%20-%20x)
We now combine the terms to get:
![2 = 4x](https://tex.z-dn.net/?f=2%20%3D%204x)
Divide both sides by 4
![x = \frac{2}{4} = \frac{1}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20)
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
