### Instruction:
 Melissa anarekebisha viatu vyake. Kwa kila kiatu, inamchukua dakika 5 kubadilisha kifungo na dakika 10 kusawazisha kisigino. Melissa anatumia muda gani jumla kwenye mradi huu?


### Response:
 Kwanza tafuta muda jumla Melissa anatumia kwa kila kiatu: dakika 5 + dakika 10 = <<5+10=15>>15 dakika
Kisha mara mbili idadi ya viatu * muda kwa kila kiatu ili kupata muda jumla anatumia: viatu 2 * dakika 15/kiatu = dakika 30
