All you need to do to answer this equation is to continually add 3/4 until you get 9 1/2 or as close as you can get without going over. In this case if you keep on adding 3/4 you will get only up to 9 because you cant go over your value of 9 1/2. Your answer is D.
Answer:
(D) 360 m
Step-by-step explanation:
We let x be the number of tablespoon of chemical solution (c) that is to be added to a certain amount of water. The equation that would best represent the given scenario is,
B = 1200 - 75x
Substituting 300 to B of the equation,
300 = 1200 - 75x
The value of x from the equation is 12. Therefore, 12 tablespoon of chemical should be added per gallon. Since there are 500 gallons of water, the amount of chemical that should be added is 6000 tablespoons.
