80%<------>$1760
100%<---> (100/80) x $1760
= 5 x $440
= $2200 (original selling price)

1760 would be 80% of the original price.
(80/100)n = 1760
n = 1760 x 100/80
n = 1760 x 1.25
n = 2200

$2,200
method a (quickest way)
1760/(1-.2)=2200
method b (pretty much the same as method a; this is just step by step)
1760=x-.2x
1760=.8x
1760/.8=x
2200=x

x - 20% x = 1760 and solve for x.
80% x = 1760
x = 1760/80%
or you can write it this way:
x - 0.2 x = 1760
0.8 x = 1760
x = 1760/0.8
