Answer:
Explanation:
First, let's calculate how much paint is used for the demonstration: 1/2 gallon.
Next, we subtract the paint used for the demonstration from the total available paint: 50 gallons - 1/2 gallon = 49.5 gallons.
Now, we divide the remaining paint by the amount of paint given to each student (3/4 gallon):
49.5 gallons ÷ (3/4 gallon) = (49.5 * 4) / 3 = 198/3 = 66 students.
Therefore, the correct answer is D) 66 students can paint the mural using the given amount of paint.
