Answer:
B
Step-by-step explanation:
When flipping, the y-levels of E' and F' do not change, meaning that as they are transferred across the y-axis, they keep their parallel to the original points.
The width of the garden is 78
You just divide 7722 by 99 (which is 78)
The answer should be n= 1500
The function will be

where y is the balance, and x is the number of month.
The raph will be a line on the xy-plain which starts at the point (0, 360), and end in the point (72, 0).
Hope it helps.
