Benjamin walks 6 miles to work and 6 miles home, so he walks 6 * 2 = <<6*2=12>>12 miles to work and home.
He walks to work 5 days a week, so he walks 12 * 5 = <<12*5=60>>60 miles to work and home a week.
He walks his dog 2 times a day for 2 miles, so he walks 2 * 2 = <<2*2=4>>4 miles a day for his dog.
He walks his dog 7 days a week, so he walks 4 * 7 = <<4*7=28>>28 miles for his dog.
He walks 3 miles to the store 2 times a week, so he walks 2 * 3 = <<2*3=6>>6 miles to the store each week.
Adding his weekly 1 mile to his friend’s house, Benjamin walks 60 + 28 + 6 + 1 = <<60+28+6+1=95>>95 miles in a week.
