( 4.625, - 3.75 )
the midpoint of (x₁, y₁ ) and (x₂, y₂ ) is
[(x₁ + x₂ ),
(y₁ + y₂ ) ]
here (x₁, y₁ ) = (5.5, - 4.75 ) and (x₂, y₂ ) = (3.75, - 2.75 )
[ (5.5 + 3.75 ),
(- 4.75 - 2.75 ) ]
= (4.625, - 3.75 ) ← midpoint of HX
Answer:
150x, (x<=3)
225+75x, (x>3)
*x is the number of nights stayed.
Step-by-step explanation:
-Let the number of days stayed be x.
#If the number of days is equal to or less than 3 days, the cost is:
Hence, the cost for x>3 is given by 150x
#If the number of days is greater than 3, the the cost is calculated as:
We sum the two costs for x>3
Hence, the cost for x>3 is given by 225+75x
