Answer: Assuming you mean that the original cost was doubled and now equals $60, the camera costed $30. Assuming the camera's price has been doubled from $60, it is $120. The wording is a bit unclear, so I'm giving you both answers.
Step-by-step explanation: To find half of the price of $60, simply divide it by 2, which gives you $30.
Answer:
60
Step-by-step explanation:
![\begin{aligned}f(x) & =x^2-4\\\implies f(8) & =(8)^2-4\\& =64-4\\& =60\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7Df%28x%29%20%26%20%3Dx%5E2-4%5C%5C%5Cimplies%20f%288%29%20%26%20%3D%288%29%5E2-4%5C%5C%26%20%3D64-4%5C%5C%26%20%3D60%5Cend%7Baligned%7D)
You can write both numbers as fractions:
![6.3=\dfrac{63}{10},\quad 0.9=\dfrac{9}{10}](https://tex.z-dn.net/?f=6.3%3D%5Cdfrac%7B63%7D%7B10%7D%2C%5Cquad%200.9%3D%5Cdfrac%7B9%7D%7B10%7D)
Dividing by a fraction is the same as multiplying by its inverse, so we have
![\dfrac{63}{10}\div \dfrac{9}{10}=\dfrac{63}{10}\cdot\dfrac{10}{9}](https://tex.z-dn.net/?f=%5Cdfrac%7B63%7D%7B10%7D%5Cdiv%20%5Cdfrac%7B9%7D%7B10%7D%3D%5Cdfrac%7B63%7D%7B10%7D%5Ccdot%5Cdfrac%7B10%7D%7B9%7D)
We can cross-simplify the 10's and we have
![\dfrac{63}{10}\cdot\dfrac{10}{9}=\dfrac{63}{9}=7](https://tex.z-dn.net/?f=%5Cdfrac%7B63%7D%7B10%7D%5Ccdot%5Cdfrac%7B10%7D%7B9%7D%3D%5Cdfrac%7B63%7D%7B9%7D%3D7)
