Answer:
The cost of each computer before finance is:
Desktop: $2900.00, Laptop: $3200.00
Step-by-step explanation:
Lets say the cost of Desktop is 'D' dollars.
The cost of laptop is
dollars.
Total finance charge for 1 year is given by:
![0.06\times D+0.07 \times (D+300)=398](https://tex.z-dn.net/?f=0.06%5Ctimes%20D%2B0.07%20%5Ctimes%20%28D%2B300%29%3D398)
Solving for D we get:
.......(equation 1)
![0.13D=398-21=377](https://tex.z-dn.net/?f=0.13D%3D398-21%3D377)
![D=\frac{377}{0.13} =2900](https://tex.z-dn.net/?f=D%3D%5Cfrac%7B377%7D%7B0.13%7D%20%3D2900)
Now the cost of laptop is D+300:
![D+300=2900+300=3200](https://tex.z-dn.net/?f=D%2B300%3D2900%2B300%3D3200)
So before finance, the cost of desktop was $2900.00 and the cost of laptop was $3200.00.
P.S: You can check if your calculation is correct by plugging the values of the cost of laptop and desktop in the equation 1.
Answer:
x= 5/2, x= -3
4x^2+2x-30=0; Factor that without the 0. Then you get 2 (2x-5) (x+3)=0.
2x-5=0 x= 5/2
x+3=0 x= -3
Hope this helps! :D
