Bill needs to soak his clothes for 4 minutes to get rid of each grass stain and 7 additional minutes to get rid of each marinara stain. If his clothes have 3 grass stains and 1 marinara stain, how long does he need to soak them?
Билл бояд барои рафъ кардани ҳар як доғи чӯб 4 дақиқа ва барои рафъ кардани ҳар як доғи маринара 7 дақиқа либосҳояшро тар кунад. Агар либосҳояш 3 доғи чӯб ва 1 доғи маринара дошта бошад, ӯ чанд дақиқа бояд онҳоро тар кунад?
How long does it take to get rid of the grass stains? ** First find the total soaking time to get rid of the grass stains: 4 minutes/stain * 3 stains = <<4*3=12>>12 minutes
How long does it take to get rid of the marinara stain? ** Then add the soak time for the marinara to find the total soak time: 12 minutes + 7 minutes = <<12+7=19>>19 minutes
