15% of gross = 630
0.15 G = 630
Divide each side by 0.15 :
G = 630/0.15 = $4,200
The general Formula for a decreasing Annuity is:

For this example we have:
P = 78,000
n = 7*4 = 28
i = 8%/4 = 2% = 0.02
After substituting you can find value for R, rent.
Answer:
m = variables
+4 = Coefficients
-7 = Coefficients
and 2 and 6 are Constants
Hope this helps!
