An 80 x 130 lot measures 10,400 square feet. To convert square feet to acres, you divide by 43,560 (the number of square feet in an acre). Therefore, 10,400 square feet is approximately 0.24 acres.
80/100 = 130/X --> 80*x = 100*130 --> 80x = 13,000 --> 13,000/80 = x --> x = 162.5
130 x 80 = 10400
Subtracting 80 percent off 130 gives 130 x (1 - (80/100)) = 26.

20x=130 x=130/20 x=6.5 or 13/2
130 x 80 = 10400
80/100 = 130/X --> 80*x = 100*130 --> 80x = 13,000 --> 13,000/80 = x --> x = 162.5
130 x 80 = 10400
Subtracting 80 percent off 130 gives 130 x (1 - (80/100)) = 26.
