Answer:
The given equation is
y =
x
→ 
reciprocating both sides, we get
→ 
............(1)
→ Here x and y are Directly proportional to each other.
which means ,
→ x = k y , where k is constant of proportionality.
Or , 
= k ............................(2)
Equating (1) and (2),
k = 
Answer:
C
Step-by-step explanation:
If you multiply the top equation by 2 and the bottom equation by -5, then there will be a 10x in the first equation and a -10x in the second, which you can cancel out in the next step. Therefore, the correct answer choice is C. Hope this helps!
Answer: 62.13%
Step-by-step explanation:
Given , Salary of Mr. Palahniuk = $1190
Percentage of Salary he spent on groceries = 24%=0.24
Amount he deposited in his saving funds = $165
Amount he spent on groceries = (Percentage of Salary he spent on groceries) x (Salary )
= (0.24) (1190)
= $ 285.6
Now , Money left = (Salary) - [(Amount he deposited in his saving funds)+(Amount he spent on groceries)]
= $1190-[$285.6+$165]
= $1190 - $450.6
=$739.4
Percentage of his salary is left = (Money left )÷ (Salary) x 100
= (739.4) ÷(1190) x 100
≈62.13%
Hence, the percentage of his salary is left = 62.13%
