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!

Area of triangle=1/2×base×height
861cm^2=1/2×81×height
861=41× height
height=861/41
Height=21cm
so height of triangle is 21cm
I believe the answer is C.
93.53 - 21.41 = 72.12
If you simplify C, its answer becomes equivalent to the answer of the original problem:
(90 - 20) + (3 - 1) + (0.5 - 0.4) + (0.03 - 0.01)
70 + 2 + 0.1 + 0.02
72.12
