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

### Instruction:
Each year Dani gets 4 pairs of two pants each as pay winning the best Amazon buyer of the season. If he initially had 50 pants, calculate the number of pants he'll have in 5 years.

### Response:
 Ikiwa anapata jozi nne za suruali kila mwaka, na kila jozi ina suruali mbili, anapata suruali 4*2 = <<4*2=8>>8 kila mwaka.
Baada ya miaka mitano, idadi jumla ya suruali atakazopokea ni 5*8 = <<5*8=40>>40 suruali.
Ikiwa awali alikuwa na suruali 50, atakuwa na jumla ya suruali 50+40 = <<50+40=90>>90 baada ya miaka 5.
