After a 16% price reduction, a boat sold for $22680. What was the boats price before the reduction?
You have to read the words carefully in this problem. The value that is reduced is unknown. But we do have a MATH EQUATION that illustrates this fact from the word problem.
Let O represent the original price. so.....
O - O (.16) = 22680
.84 O = 22680 solve for O by combining like terms....(1-.16)O = 22680.....or .84 * O = 22680
divide both sides by .84 we get.... O = 27000 check.....27000 - (.16) (27000) = 22680 ....
27000 - 4320 = 22680...that checks out......
