Question

a homeowner wants to determine how much paint is needed to paint the walls of his living room. choose the two variables the homeowner should most consider when deciding how much paint is necessary. a. the cost of one gallon of paint b. the number of rooms in the house c. the number of walls in the living room d. the area of the walls in the living room e. the area that one gallon of paint will cover

Explanation:

To determine the amount of paint needed, we need to know the total area to be painted (area of the living room walls) and the coverage per gallon of paint. The cost of paint (A) is about expense, not quantity needed. The number of rooms in the house (B) is irrelevant as we're only painting the living room. The number of walls (C) alone isn't enough; we need the area of those walls. So the key variables are the area of the living room walls (D) and the area one gallon covers (E).

Answer:

D. the area of the walls in the living room, E. the area that one gallon of paint will cover
