The answer is C - f(x) = 3x + 2
Hey, Melany. To answer this problem, simply set up a proportion:
. Now let's solve for x.
- Cross multiply:![\frac{18.75*128}{100*x} --> 2400 = 100x](https://tex.z-dn.net/?f=%5Cfrac%7B18.75%2A128%7D%7B100%2Ax%7D%20--%3E%202400%20%3D%20100x)
- Isolate x:
![\frac{2400}{100} = \frac{100x}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B2400%7D%7B100%7D%20%3D%20%5Cfrac%7B100x%7D%7B100%7D)
This means that x = 24.
