Question 124903: I don't know if I am just making it harder than it is or just don't get it....Help
The long's sold their vacation home for $88,000. If they made a profit of 10 percent, what was the ORIGINAL cost of the property?
Answer by checkley71(8403)   (Show Source):
You can put this solution on YOUR website! LET X BE THE ORIGINAL PRICE.
88,000=X+.1X THIS EQUATION SAYS THAT 88,000 IS THE ORIGINAL PRICE PLUS 10% OF THE ORIGINAL PRICE.
NOW WE SOLVE FOR X.
88,000=1.1X
X=88,000/1.1
X=$80,000WAS THE ORIGINAL PRICE OF THE HOUSE.
PROOF
80,000*1.1=88,000
88,000=88,000
