Answer:
$400 
OR 
Step-by-step explanation:
$400 stays the same, 72 cents is 72/100. Simplify and voila
For 3 days....
option 1 : 25(3) + 0.10m = 75 + 0.10m
option 2 : 60(3) = 180
180 < 75 + 0.10m
180 - 75 < 0.10m
105 < 0.10m
105 / 0.10 < m
1050 < m.....this is minutes, we need hrs
1050/60 < m
17.5 < m.......the guest would have to spend more then 17.5 hrs
I’m pretty sure it’s n=-5
Hope this helps have a great day
The computation shows that the price of the used computer is $75.

Answer:
This is a reflection about the x-axis.
Step-by-step explanation:
A reflection about the x-axis has the rule
[x,y]-> [x,-y].
Therefore
M[x,y] = [x,-y}
Let M=
|a b|
|c d|
Then the matrix multiplication gives
ax+by=x.............(1)
cx+dy=-y............(2)
Solving the previous equations (1) and (2) gives
a=1, b=0
c=0, d=-1
giving M as
|1 0|
|0 -1|
