Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Mikaela was repainting her bathroom. She bought 16 containers of paint to cover the four equally-sized walls. At the last minute, she decided to put tile on one wall in the bathroom and paint flowers on the ceiling with one container of paint instead. How many containers of paint will she have left over?

### Response:
 Mikaela angehitaji kontena 16 / 4 = <<16/4=4>>4 kwa kila ukuta.
Kupaka kuta 3, atatumia 3 * 4 = <<3*4=12>>12 kontena.
Baada ya kutumia kontena 1 kwa dari, atakuwa na kontena 16 - 12 - 1 = <<16-12-1=3>>3 ya rangi yaliyobaki.
