Answer 1

yikes i got lost after the first line

Answer 2

but the trick to doing a problem like this is to use an actual number. since the answer does not depend on the number used, whatever you get for that number will be the right answer

Answer 3

we could say the "selling price" is 200
then increase it by 25% and get 250 for the "marked" price

take half of the "marked" price get 125 for the cost

Answer 4

so it cost 125, sells for 200
profit is 75 and \(\frac{75}{125}=\frac{3}{5}=.6=60\%\) now it it works for 200 it has to work the same way for any number
