![B =120](https://tex.z-dn.net/?f=B%20%3D120)
Step-by-step explanation:
Given
Represent Kitchen with K and Bedroom with B.
So:
![K = 50ft^2](https://tex.z-dn.net/?f=K%20%3D%2050ft%5E2)
<em />
<em> --- 10 more than 1/3 of Bedroom area</em>
Required
Determine the bedroom area
The expression of K and B has been determined above.
The next step is to substitute 50 for K in the second equaion
![K = 10 + \frac{1}{3}B](https://tex.z-dn.net/?f=K%20%3D%2010%20%2B%20%5Cfrac%7B1%7D%7B3%7DB)
![50 = 10 + \frac{1}{3}B](https://tex.z-dn.net/?f=50%20%3D%2010%20%2B%20%5Cfrac%7B1%7D%7B3%7DB)
Multiply through buy 3
![3 * 50 = 3 * 10 +\frac{1}{3}B * 3](https://tex.z-dn.net/?f=3%20%2A%2050%20%3D%203%20%2A%2010%20%2B%5Cfrac%7B1%7D%7B3%7DB%20%2A%203)
![150 = 30 +B](https://tex.z-dn.net/?f=150%20%3D%2030%20%2BB)
Make B the subject
![B =150 - 30](https://tex.z-dn.net/?f=B%20%3D150%20-%2030)
![B =120](https://tex.z-dn.net/?f=B%20%3D120)
<em>Hence, the area of the bedroom is 120ft^2</em>
Question: An aquarium is on sale for $59.50. If this price represents a 15% discount from the original price, what is the original price?
First, you multiply the sale price and the 15% discount
![$59.50*.15 = [tex]$8.92](https://tex.z-dn.net/?f=%2459.50%2A.15%20%3D%20%5Btex%5D%248.92)
[/tex] (To change the percent to a decimal, you take out the percentage sign and divide by 100)
Now add $59.50 to $8.92
![59.50+8.92=$68.43](https://tex.z-dn.net/?f=59.50%2B8.92%3D%2468.43)
Answer:
$68.43 (when rounded to the nearest cent)
or
$68 (when rounded to the nearest dollar)
or
$70 (when rounded to the nearest ten dollar)
