If you can graph in slope intercept, your new equations would be: y= -2x-1 and y= 2/3x-3.
Just graph those now since it should be easier.
A) 1000/239 = 4.something
Ms. Ferguson could book the room for 4 nights
B) 6 x 239 = 1434
1450/1434 = 1.01
Ms Ferguson was off by 1%
C) 2075/1589 = 1.3058
The price increase was by 31%
D) 2075/1.3 = 1596.153
The price that was found was $1596.15
since the area of the rectangle is 13 square inches and the length is 3.25 inches subtract 3.25 from 13

which makes your width 9.75
to find the perimeter you add
9.75 + 3.25 + 9.75 + 3.25= 26.5
The perimeter of the rectangle is 26.5
