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. How much will siyabonga spend on tiles?

First, Siyabonga needs to calculate how many tiles he needs. Let's say he needs 100 tiles.

10% more tiles would be 110 tiles (100 + 10% of 100).

Each box contains 6 tiles, so Siyabonga would need 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 Siyabonga would spend 19 x R234 = R4446 on tiles.

Step 1: Calculate the number of tiles needed

Let's assume the number of tiles required is x. Since the builder recommends buying 10% more tiles, Siyabonga will need to buy 110% of x tiles.

Number of tiles needed = 110% of x = 1.1 - x

Step 2: Calculate the number of boxes needed

Each box contains 6 tiles. So, the number of boxes needed is the number of tiles needed divided by 6.

Number of boxes needed = Number of tiles needed / 6 = 1.1 - x / 6

Step 3: Calculate the cost of the tiles

Each box of tiles costs R 234. So, the total cost of the tiles is the number of boxes needed multiplied by the cost per box.

Total cost of tiles = Number of boxes needed - Cost per box = 1.1 - x / 6 - R 234

Step 4: Calculate the cost

Substitute the value of x with the actual number of tiles required.

For example, if Siyabonga needs 50 tiles, then the calculation would be:

Total cost of tiles = 1.1 - 50 / 6 - R 234 = R 2,062.50

Therefore, Siyabonga will spend R 2,062.50 on tiles.
