Answer:
20%
Step-by-step explanation:
We can start by finding out how much the price of the television was reduced by.
250 - 200 = 50
Now, we need to know what percent of 250 is 50? Let x represent the percent of 250 that is 50. Using this, we can set up an equation:
<u />
Notice that a percentage can also be written as that number over 100.


Reduce the fraction (250 and 100 have a common factor of 10)

Reduce the fraction again (25 and 10 have a common factor of 5)

Multiply both sides by two

Divide both sides by 5

Therefore the price of the television was reduced by 20%.
