Question 1072812
if a coat is marked as 25% off and you pay $90 how much is the original price
————————————————————————————————
Let x = original price
"25% of x" is 0.25x
"25% off of x" is  1x-0.25x = (1-0.25)x = 0.75x  
—

We know  $90 = 0.75x 
Divide both sides by 0.75:    
 $90/0.75 = x
 $120 = x

Original price of coat was ${{{highlight(120)}}}
