Question

Noah is designing a set for a theater production. He has 150 bricks and wants to build a chimney. The arch takes 4 times as many bricks. He sets 15 aside to save for broken ones. How many bricks are needed for the arch?

A) 30
B) 45
C) 60
D) 75

Answer 1

Noah needs 540 bricks for the arch.

Step-by-step explanation:

Let's start by finding the number of bricks that Noah sets aside for broken ones. He sets aside 15 bricks. Therefore, he has 150 - 15 = 135 bricks left to use.

Next, we need to find the number of bricks needed for the arch. The arch takes 4 times as many bricks as the chimney, which means it requires 4 * 135 = 540 bricks.

Therefore, Noah needs 540 bricks for the arch.
