Question 1034741
Problem:

A suit was on sale for $142.50, marked down 25% from its original price. What was the original price of the suit? 


----------------------------------------------------------------------------------------


Steps:


Let x = original price of the suit (in dollars)


x is the original price
we take 25% off the original price to get the discount sale price (142.50)
so,


(original price) - (25% of original price) = discount price
(x) - (25% of x) = 142.50
x - 0.25*x = 142.50
1*x - 0.25*x = 142.50
0.75*x = 142.50
0.75*x/0.75 = 142.50/0.75 <font color=blue>divide both sides by 0.75 to isolate x</font>
x = 190

Answer: The original price of the suit was <font color=red>$190</font>
