What is percentage?
The term "percentage" comes from the Latin phrase "per centum," meaning means "by the hundred." Percentages is fractions with a denominator of 100.
In other terms, it is the relationship between portion and whole in which the value of the whole is always assumed to be 100.
Calculating a percentage implies determining a portion of a whole in term of 100. A percentage can be calculated in two ways:
- The unitary technique is used.
- By adjusting the fraction's denominator to 100.
- It must be noted that second method of percentage calculation is not employed when the denominator isn't a factor of 100. In such circumstances, we employ the unitary technique.
Now, according to the question;
Given that prices fall about 20% every decade;
Thus, 100% - 20% = 80%
He paid $250 million for a batmobile twenty years ago.
Let Bruce to receive x millions of dollars for the batmobile.
⇒ 80% of x = 80/100 × x = 4/5 x
⇒ x = 250(4/5)(4/5)
⇒ x = 250(16/25)
⇒ x = 160
As a result, Bruce will receive 160 millions of dollars for such batmobile.
