Percentage is wrong

[Scott]

I'm trying to get a percentage increase on a dollar amount but the totals are
not correct.
$30 is target.
+$U$2-D5 is Formula (10%)
$33.33 answer

 

[David Biddulph]

$30 is 10% less than $33.33
If you want 10% more than $30, it is $30*(1+10%), in other words $33

It is the same situation as the fact that doubling something adds 100%, but
halving something subtracts 50%.

Thank you very much I thought to much about the formula rather than the
math.
