Answer: g = 40f
Step-by-step explanation:
Since one water filter will clean 40 gallons of water, the equation that can be used to find g, the total number of gallons that will be cleaned by any number of filters f will be gotten by multiplying f by 40. This will be:
g = f × 40
g = 40f
For example, the gallons of water that 4 water filters will clean will be:
= 40f
= 40 × 4
= 160 gallons
