3276800/8 = 409600 (how many bacteria in an hour)
Then just multiply that number by the amount of hours you want to solve for
9 hours = 3686400
10 Hours = 4096000
we have
10 3/11 + 3 9/11=(10+3)+(3/11+9/11)=13+(12/11)=13=(13=(
The independent variable (the one they want) is the # of hours worked, since that determines the price.
