Answer 1

To find the cost of painting Marion's bedroom, calculate the total area to be painted and multiply by the cost per square foot of the paint.

Step-by-step explanation:

To find the cost of painting the four walls and ceiling of Marion's bedroom, we need to calculate the total area that needs to be painted. First, let's find the area of each wall. Since the walls are 8 feet in height, the area of each wall is 8 feet multiplied by the width of the room. The total area of the four walls is then 4 times the area of one wall. Next, let's find the area of the ceiling, which is the length of the room multiplied by the width of the room. Finally, we add the area of the four walls and the area of the ceiling to get the total area that needs to be painted. Next, we multiply the total area by the cost per square foot of the paint to get the total cost. Since the paint costs between $0.75 and $0.90 per square foot, a reasonable cost for Marion to paint the four walls and ceiling of her bedroom would be between $X and $Y.
