Answer:
V=8250-18*c
Step-by-step explanation:
The equation will be:

Where:
- V is the volume of corn in the silo after loading begins.
- 8250 is the initial volumen on the silo before the loading begins.
- 18 is the 18 cubic feet per hour given as rate of loading.
- c is the number of hour elapsed after loading begins.
To find the volume, V, of the corn in the silo c hours after loading begins, we substract from the initial volume the quantity of corn loaded and this is 18*c, that is the number of hour elapsed multiplyed by the rate of loading.
