(2) Answers

ok you wash 38 in 2 hours now multiply 38 by 3 and that's the total you wash in 6 hours ( the 3 is the amount of 2 hour shifts total) finally divide 38 by 2 and then add that to the total you wash in 6 hours


proportion: 38/2•x/7 cross multiply: (7)(38)=2x simplify: 266=2x divide: x=133 133 windows
