The builder recommends to siyabonga that he buy's 10% more tiles than required in case of breakages. The tiles he likes are R 234 for a box of 6 tiles.by calculation how many tiles are needed?

First, Siyabonga needs to calculate how many tiles he needs to buy. Let's assume he needs 100 tiles for his project.

If he needs 100 tiles, he should buy 10% more, which would be 110 tiles.

Each box contains 6 tiles, so he would need to buy 110/6 = 18.33 boxes of tiles.

Since he can't buy a fraction of a box, he would need to round up to 19 boxes.

Each box costs R234, so he would spend 19 x R234 = R4446 on tiles.

Step 1: Calculate the number of tiles required.

Assume Siyabonga needs "x" tiles.

Step 2: Calculate the number of tiles to be purchased with 10% excess.

Tiles to be purchased = Tiles required + 10% of tiles required
Tiles to be purchased = x + 0.1x = 1.1x

Step 3: Calculate the number of boxes required.

Since each box contains 6 tiles, the number of boxes required is:
Boxes required = Tiles to be purchased / Tiles per box
Boxes required = 1.1x / 6

Step 4: Calculate the cost of tiles.

Cost of tiles = Cost per box - Boxes required
Cost of tiles = R 234 - (1.1x / 6)

Step 5: Solve for x.

Siyabonga needs to provide the number of tiles required (x) to determine the cost of tiles.
