madeline studies honeybees. every week she weighs the same honeybee hive, the first week the hive weighs 11.607 kilograms. its w
fomenos
So, we already know that one hive has a weight of 11.607kg and .204kg is add each week, so we add on .204kg times, w, representing weeks onto 11.607kg and our t is our total of weight of a hive with respect to weeks

w = weeks \\ t = total \: weight \: with \: respect \: to \: weeks
So in this case our w is 7.5 weeks and now we evaluate t

w = 7.5 \: weeks \\ t = ?
Solve
11.607kg + .204kg(w) = t \\ 11.607kg + .204kg(7.5) = t \\ t = 13.137kg
Answer:

Hive's weight will increase by 1.53kg in 7.5 weeks to 13.137kg
