Find the increase in the sale.
It is for 240$. Then find for 100$
(That is, multiply 100 with the increase and divide it by 240.
The answer you got is the percentage of the sale sin increase.

First make an equation Where x=percentage
240 + x(240) = 320 ;
x(240) = 320 - 240
x(240) = 80
x= 80/240
x = .33333 * 100 ---------- To get decimal to percentage
x = 33.3333%
to prove this just substitute percentage in originalequation
240 + .3333333(240) = 320
