She needs 485 bricks

Each stack is 24 bricks

The number of stacks she will need is the total number of bricks divided by how many she will get per stack.

Needed stacks = 485 / 24 = 20 5/24 20.21 ( to 2 d.p.)

However, we can't get 5/24 of a stack. So we must go to the closest number of whole stacks, however 20 stacks is not enough for the 485 needed bricks, so we instead must go up to 21 stacks

∴ Needed stacks = 21
