X*10%=15
X=15/10% = 15/0.10=150
Percent of change
Percentage change between two numbers A & B can be calculated
as:
(B-A)/A * 100
For example, if a game price increases in value from $10 to $12
the percentage increase is:
(12-10)/10 * 100 = 2/10 *100 = 0.2*100 = 20 percent
Alternatively, if a game price decreases in value from $10 to $9 the
percentage decrease is:
(10-9)/10 * 100 = 0.1*100 = 10 percent
