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? Let's be accurate as possible.
First find the total soaking time to get rid of the grass stains: 4 minutes / stain * 3 stains = 12 minutes. Then add the soak time for the marinara to find the total soak time: 12 minutes + 7 minutes = 19 minutes.
The answer: 19.
