Q. Peter is building a brick house. He built

3

walls using

803

bricks each. Another wall used

998

. A fireplace took

247

and the chimney took

452

. Peter works out that he has used a total of

2,500

bricks so far. Does that sound about right?

\newline

Choices:

\newline

(A)Yes.

\newline

(B)No, it is much too high.

\newline

(C)No, it is much too low.

Calculate total bricks for walls: Calculate the total number of bricks used for the three walls. Each wall used $803$ bricks, so multiply $803$ by $3$ .
Add bricks for fourth wall: Add the bricks used for the fourth wall to the previous total. The fourth wall used $998$ bricks.
Add bricks for fireplace: Add the bricks used for the fireplace to the current total. The fireplace used $247$ bricks.
Add bricks for chimney: Add the bricks used for the chimney to the current total. The chimney used $452$ bricks.
