So
100%=original
25% discount
100-25=75
it is 180 sale
75%=180
find 100%
a hack is to recognize that 75/3 times 4=100 so
75%=180
divide 3
25%=60
times 4
100%=240
the real way is proportions
75:180 =100:x
75/180=100/x
multiply both sides by 180x
75x=18000
divide 75
x=240
origitnal price=$240

It is a decimal that does not terminate. 1/3 is equivalent to .3333333333 and so on. it never ends
Alright, so we have the difference = 4500-2800=1700. To find the percent increase, we do 1700/2800=around 0.61 = around 61% percent
