2800 + 1.18x = y
x = monthly sales
y = monthly income
y needs to be at least 6400 so that means;
2800 + 1.18x ≥ 6400
1.18x ≥ 6400 - 2800
x ≥ (6400 -2800) / 1.18
x ≥ 3050
So she needs to earn at least 3050, which means <span>≥ 3050</span>
Sry if i’m wrong but i’m pretty sure he can spend $200 since you alr take out 30.
Answer:

Step-by-step explanation:
<em>Hey there!</em>
3x * x = 3x^2
3x * 2x = 6x^3
So 3x is a factor of 3x^2 - 6x^3.
