$2000. If $1600 has already had 20% taken off, then the $1600 is 80% of the original price. $1600/80x100=$2000. Check backwwards. $2000 x .20 = $400. $2000 - $400 = $1600

1,920

x-0.2x=1600 0.8x=1600 x=2000

I will not give you the answer. Here's a short procedure: We're trying to find out X 20% can be expressed as 0.80 of a unit. (1) (same as 25% is 0.75, 50% is 0.50, etc) so if 1,600 is .80 X is 1 Multiply 1,6000 by 1, then divide into .80
