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

### Instruction:
Sabrina is collecting herbs to make a poultice for her grandmother. She needs twice as many basil leaves as sage leaves and 5 fewer sage leaves than verbena leaves. If she needs 12 basil leaves, how many leaves total does she need?

### Response:
 Kwanza tafuta idadi ya majani ya sage ambayo Sabrina anahitaji: 12 basil / 2 basil/sage = <<12/2=6>>6 sage
Kisha ongeza 5 ili kupata idadi ya majani ya verbena anayohitaji: 6 sage + 5 = <<6+5=11>>11 verbena
Hatimaye, jumlisha majani yote tofauti ili kupata idadi ya jumla: 6 sage + 11 verbena + 12 basil = <<6+11+12=29>>29 majani
