Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. How much money did she save????
andrey2020 [161]

Given:

Normal price of a tv = $200

Coupon = 25% off

To find:

The money saved by Katherine.

Solution:

Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.

Saving=25\%\text{ of }200

Saving=\dfrac{25}{100}\times 200

Saving=25\times 2

Saving=50

Therefore, the money saved by Katherine is $50.

72 + 8x + 18x = 36x
ArbitrLikvidat [17]
72 + 8x + 18x = 36x&#10; 

72+26x=36x&#10; 

72=36x-26x&#10;  \text{Subtract 26x from both sides} 

72=10x&#10; 

\text{Divide both sides by 10} 

x=36/5
