Answer:
$127.68
Step-by-step explanation:
Rate= 6.4%
Principal= $120
Time = 1 year
Required
The final amount A
Step two
A=P(1+rt)
substitute
A=120(1+0.064*1)
A=120(1.064)
A=120*1.064
A=$127.68
Hence the final amount is $127.68
Answer:
Required value of k is 43% .
Explanation:
Lets assume original regular price of sports jacket = x
On sale , price of jacket is reuced by 30%
Sales price = x - 30% 0f x
![\text{{Sales price}} = x - 30\frac{1}{100}\times x](https://tex.z-dn.net/?f=%5Ctext%7B%7BSales%20price%7D%7D%20%3D%20x%20-%2030%5Cfrac%7B1%7D%7B100%7D%5Ctimes%20x)
Sales price= x – 0.30x
Sales price= 0.70x
Once sales is over price of jacket is increased by k%
That is
Sales price + k% of Sales price
= 0.70x + k% 0.70x
Also given after increasing to k% , price becomes equal to regular price
=> 0.70x + k% of 0.70x = original regular price
=> ![0.70x + \frac{k}{100}\times0.70x = x](https://tex.z-dn.net/?f=0.70x%20%2B%20%5Cfrac%7Bk%7D%7B100%7D%5Ctimes0.70x%20%3D%20x)
=>![0.70 + \frac{0.70}{100}k = 1](https://tex.z-dn.net/?f=0.70%20%2B%20%5Cfrac%7B0.70%7D%7B100%7Dk%20%3D%201)
=>![\frac{0.70}{100}k=1-0.70](https://tex.z-dn.net/?f=%5Cfrac%7B0.70%7D%7B100%7Dk%3D1-0.70)
=> 0.70k = 100 x 0.30
=>
that is 43
Hence required value of k is 43% .
