Answer: each shirt is 8 dollars so for every 1 there is 8 tje percent would be 25% = 1 shirt or $8.00 Hope this helps!
Step-by-step explanation:
Answer:
HK = 16
Step-by-step explanation:
12^2+x^2=20^2
x = HK
Invested amount (P) = $300.
Time in years (t) = 2 years.
Balance after 2 years (A) = $329.49.
Let us assume rate of interest = r % compounds annually.
We know, formula for compound interest
![A=P(1+r)^t](https://tex.z-dn.net/?f=A%3DP%281%2Br%29%5Et)
Plugging values in formula, we get
![329.49=300(1+r)^2](https://tex.z-dn.net/?f=329.49%3D300%281%2Br%29%5E2)
![\mathrm{Divide\:both\:sides\:by\:}300](https://tex.z-dn.net/?f=%5Cmathrm%7BDivide%5C%3Aboth%5C%3Asides%5C%3Aby%5C%3A%7D300)
![\frac{300\left(1+r\right)^2}{300}=\frac{329.49}{300}](https://tex.z-dn.net/?f=%5Cfrac%7B300%5Cleft%281%2Br%5Cright%29%5E2%7D%7B300%7D%3D%5Cfrac%7B329.49%7D%7B300%7D)
![\left(1+r\right)^2=1.0983](https://tex.z-dn.net/?f=%5Cleft%281%2Br%5Cright%29%5E2%3D1.0983)
Taking square root on both sides, we get
![1+r=\sqrt{1.0983}](https://tex.z-dn.net/?f=1%2Br%3D%5Csqrt%7B1.0983%7D)
![\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}](https://tex.z-dn.net/?f=%5Cmathrm%7BSubtract%5C%3A%7D1%5Cmathrm%7B%5C%3Afrom%5C%3Aboth%5C%3Asides%7D)
![1+r-1=\sqrt{1.0983}-1](https://tex.z-dn.net/?f=1%2Br-1%3D%5Csqrt%7B1.0983%7D-1)
![r=\sqrt{1.0983}-1](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B1.0983%7D-1)
![r=1.048-1](https://tex.z-dn.net/?f=r%3D1.048-1)
r=0.048.
Converting it into percentage by multiplying by 100.
r=0.048 × 100
r = 4.8 %
Therefore, the rate of interest on the account is 4.8% compounds annually.
