Answer:

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

A 75% increase followed by a 50% decrease

stiv31 [10]

Answer:

12.5% decrease

Step-by-step explanation:

Let X be the initial value

75% increase is 175% of X

= 1.75X

50% decrease = 0.5

0.5(1.75X)

0.875X (less than X, so decrease)

87.5% of X

100 - 87.5 = 12.5% decrease
