Answer:
B) Smartphones
Step-by-step explanation:
In order to answer this question we need to find the total revenue for the laptops and smartphones.
Let's start with the laptops.
Given:
- 200 laptops/month
- $499 per laptop
To find the total revenue of all these laptops we need to multiply 200 by 499.

Therefore, the total revenue of the laptops alone is $99,800.
Now, let's do the smartphones.
Given:
- 350 smartphones/month
- $399 per smartphone
To find the total revenue of all these smartphones we need to multiply 350 by 399.

Therefore, the total revenue of the smartphones alone is $139,650.
Comparing the two revenues we see that the smartphones generate more sales in dollars.
Hope this helps!

Answer:
y=x-3
Step-by-step explanation:
slope=4+2/-5-1=-1
perpendicular slope= negative reciprical=1
y=x+b
midpoint on perpendicular bisector= (-5+1/2, 4-2/2)=(-2,1)
substitution-2=1+b, b=-3
y=x-3
90 for the first one
120 for the second one
