Answer:
![a=6](https://tex.z-dn.net/?f=a%3D6)
Step-by-step explanation:
Given equation:
![-8+\sqrt{5a-5}=-3](https://tex.z-dn.net/?f=-8%2B%5Csqrt%7B5a-5%7D%3D-3)
Solving for unknown variable ![a](https://tex.z-dn.net/?f=a)
Adding 8 both sides by additive property of equality.
![+8-8+\sqrt{5a-5}=-3+8](https://tex.z-dn.net/?f=%2B8-8%2B%5Csqrt%7B5a-5%7D%3D-3%2B8)
![\sqrt{5a-5}=5](https://tex.z-dn.net/?f=%5Csqrt%7B5a-5%7D%3D5)
Squaring both sides to remove the square root.
![(\sqrt{5a-5})^2=5^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B5a-5%7D%29%5E2%3D5%5E2)
![5a-5=25](https://tex.z-dn.net/?f=5a-5%3D25)
Adding 5 both sides by additive property of equality.
![5a-5+5=25+5](https://tex.z-dn.net/?f=5a-5%2B5%3D25%2B5)
![5a=30](https://tex.z-dn.net/?f=5a%3D30)
Dividing both sides by 6 to isolate ![a](https://tex.z-dn.net/?f=a)
![\frac{5a}{5}=\frac{30}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B5a%7D%7B5%7D%3D%5Cfrac%7B30%7D%7B5%7D)
∴ ![a=6](https://tex.z-dn.net/?f=a%3D6)
Answer:
C. ![x\geq 55000](https://tex.z-dn.net/?f=x%5Cgeq%2055000)
Step-by-step explanation:
Let x be the total monthly sales.
We have been given that a salesperson earns a salary of $700 per month plus 2% of the sales. The salesperson want to have a monthly income of at least $1800.
This means that 700 plus 2% of total monthly sales should be greater than or equal to 1800. We can represent this information in an equation as:
![700+(\frac{2}{100})x\geq 1800](https://tex.z-dn.net/?f=700%2B%28%5Cfrac%7B2%7D%7B100%7D%29x%5Cgeq%201800)
![700+0.02x\geq 1800](https://tex.z-dn.net/?f=700%2B0.02x%5Cgeq%201800)
Let us solve our inequality to find the monthly sales (x).
Subtract 700 from both sides of our inequality.
![0.02x\geq 1100](https://tex.z-dn.net/?f=0.02x%5Cgeq%201100)
Divide both sides of inequality by 0.02.
![\frac{0.02x}{0.02}\geq \frac{1100}{0.02}](https://tex.z-dn.net/?f=%5Cfrac%7B0.02x%7D%7B0.02%7D%5Cgeq%20%5Cfrac%7B1100%7D%7B0.02%7D)
![x\geq \frac{1100}{0.02}](https://tex.z-dn.net/?f=x%5Cgeq%20%5Cfrac%7B1100%7D%7B0.02%7D)
![x\geq 55000](https://tex.z-dn.net/?f=x%5Cgeq%2055000)
Therefore, the total monthly sales must be greater than or equal to 55,000 and option C is the correct choice.
