Lets say the dollar amount is 'x'
x * 20/100 = 85/100
20x = 85
x=85/20
==> x=4.25

Ok, try ratio and proportion.
20% of a sum of money = $0.85
100% = 5 x $0.85 = $4.25
Why multiply by 5? Cos 100% is 5 times 20%, and the total of anything is always 100%.
Hope this helps :)

0.85 = 0.2 times x, since 20% = 0.2. Solve for x by dividing both sides by 0.2.
x = $4.25
