Answer:
Therefore, Jeremy will need 55.35 gallons of brown material and 2.85 gallons of green material.
Explanation:
To find out how much brown material Jeremy will need, we need to determine the value of variable A in the table. We can do this by adding up the values in the brown material column: 12.75 + 18.6 + 24 = 55.35 gallons.
Next, we need to determine the value of variable C, which represents the total amount of material in the composting container. We can find this by adding up the values in the total column: 32 + 46 = 78 gallons.
Since Jeremy needs a total of 64 gallons of compost, we can set up the following equation: A + C = 64.
Substituting the values we found earlier, we have: 55.35 + C = 64.
To solve for C, we subtract 55.35 from both sides of the equation: C = 64 - 55.35 = 8.65 gallons.
Now that we know the value of C, we can subtract it from the total amount of green material to find out how much green material Jeremy will need. From the table, we can see that the total green material is represented by variable D, which is 11.5 gallons.
Subtracting C from D, we get: D - C = 11.5 - 8.65 = 2.85 gallons.
