You can
put this solution on YOUR website!lets call the new price

and the old price

. Let's look at the statements one by one
if a price is now 220% more than it was before
Percentages are always over 100, so 220% is 220/100 = 2.2. That's of the old price though, so it is

more than the old price. So the new price is

3.2 = 320/100 so the new price is 320% of the old price, yes.
and what it was before is 31.25% of what it is now
What is was before is

, and what it is now is

. To work out a percentage like this we divide the two things and times by 100. So what we need to do

. But we know that

from above, we substitute and get

There is an

on the top and bottom of this division, so it cancels to give 100/3.2 which is 31.25, so again the answer is yes.
