Answer: c = 72
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
![(c)/(8) = 9](https://img.qammunity.org/2021/formulas/mathematics/college/2s9dyv6m6x1jbfoe68nqtqy28jp7ixc91y.png)
Multiply both sides by 8.
![c = 9 * 8](https://img.qammunity.org/2021/formulas/mathematics/college/wvk7z1ugaj45zpm5ynp24ur4si5bgjqv86.png)
Multiply 9 and 8 to get, you guessed it, 72!
