So to start you will need to divide by -5 then -5 divided by -5 cancelle
- Cost of unbleached flour=14(5)=70
Now
Let required bleached flour be x kg
Then
![\sf\longmapsto 8x+70=6x](https://tex.z-dn.net/?f=%5Csf%5Clongmapsto%208x%2B70%3D6x)
![\sf\longmapsto 8x-6x=70](https://tex.z-dn.net/?f=%5Csf%5Clongmapsto%208x-6x%3D70)
![\sf\longmapsto 2x=70](https://tex.z-dn.net/?f=%5Csf%5Clongmapsto%202x%3D70)
![\sf\longmapsto x=35kg](https://tex.z-dn.net/?f=%5Csf%5Clongmapsto%20x%3D35kg)
There are two main types of exponential functions: exponential growth<span> and </span><span>exponential decay</span>
