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:
The total volume of the water in the tank after 20 minutes = 1220 gallons
Step-by-step explanation:
Rate of water pumped into the tank r (t) = 30 (1 - )
Initial volume of water in the tank = 800 gallons
The water in the tank after 20 minutes = Initial volume of water in the tank + Volume of water being pumped in the tank
=
Where a = 0 , b = 20
Put the value of r (t) in above equation we get
=
=
=
= 420 gallon
Now, total volume in the tank
Therefore the total volume of the water in the tank after 20 minutes = 1220 gallons
