The computer costs $304 now.
Step-by-step explanation:
Given,
Cost of computer = $400
First discount = 20%
Amount of discount = 20% of $400
Amount of discount = ![\frac{20}{100}*400=\frac{8000}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B100%7D%2A400%3D%5Cfrac%7B8000%7D%7B100%7D)
Amount of discount = $80
Price after first discount = 400-80 = $320
Additional discount = 5%
Amount of additional discount = 5% of price after first discount
Amount of additional discount = ![\frac{5}{100}*320=\frac{1600}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B100%7D%2A320%3D%5Cfrac%7B1600%7D%7B100%7D)
Amount of additional discount = $16
Final cost = 320-16 = $304
The computer costs $304 now.

For this case we have that by definition the time is given by:
![t=\frac{d}{v}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bv%7D)
Where the variable "d" represents the distance and "v" represents the speed.
So, first we need to know the total distance:
![d=(v)(t)](https://tex.z-dn.net/?f=d%3D%28v%29%28t%29)
![d=(60)(8)](https://tex.z-dn.net/?f=d%3D%2860%29%288%29)
![d=480 mi](https://tex.z-dn.net/?f=d%3D480%20mi)
Then, the time for 75mph is given by:
![t=\frac{480}{75}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B480%7D%7B75%7D)
![t=6,4](https://tex.z-dn.net/?f=t%3D6%2C4)
Answer:
6,4 hours
Answer:
Reduce 6 to the lowest common denominator
Step-by-step explanation:
54/9 × 5/9
7+0 5+2 because 7+0 = nothing but 5+2= 7
By looking at it, I can tell the second expression is greater due to a a large postive number that's being added to it. Let's solve.
-12+6=-6-4=-10
-34-3=-37+39=2
So, -34-3+39 is greater.
