A wall that is 12 feet wide and 10 feet high is to be painted. A blackboard that is 5 feet wide and 3 feet high is affixed to the wall and is the only portion of the wall that will not be painted. The area of the portion that will be painted is how many square feet?

(A) 28

(B) 30

(C) 45

(D) 49

(E) 105

The total area of the wall is 12 x 10 = 120 ft^2 and the area of the blackboard is 5 x 3 = 15 ft^2.

Thus, the area of the wall that will be painted is 120 - 15 = 105 ft^2.

Answer: E
