Given that <span>the average volume of water that flows over the falls each second is
![4.8 \times 10^5](https://tex.z-dn.net/?f=4.8%20%5Ctimes%2010%5E5)
gallons.
There are 3,600 seconds in one hour.
Thus, in one hour,
![4.8 \times 10^5\times3600=17280\times10^5=1.728\times10^9](https://tex.z-dn.net/?f=4.8%20%5Ctimes%2010%5E5%5Ctimes3600%3D17280%5Ctimes10%5E5%3D1.728%5Ctimes10%5E9)
gallons of water </span><span>flows over the falls.
</span>Therefore, the amount of water that flows over the falls is <span>
![1.728\times10^9](https://tex.z-dn.net/?f=1.728%5Ctimes10%5E9)

Answer:
Laptop: $2,270
Desktop: $1,820
Step-by-step explanation:
Let L identify the laptop price and D the desktop price.
We can first say:
L = D + 450 ( the laptop cost $450 more than the desktop)
Then we can say:
0.09 D + 0.06 L = 300 (The total finance charges for one year were $300)
Then we substitute L by its value from first equation into the second equation:
0.09 D + 0.06 (D + 450) = 300
0.09 D + 0.06 D + 27 = 300
0.15D = 273 (removed 27 on both sides, and simplified left side)
D = 1,820
The cost of the desktop was $1,820
The cost of the laptop was $2,270 (price of desktop + $450)
