Question 642520

Each person produces 3.5 pounds of trash a day, so 2 people would produce 7 lbs (or 3.5lbs times 2), 3 people would produce 10.5 lbs (or 3.5 times 3) and so on. 

Realizing this pattern gives us an expression for the number of pounds of trash a family with m members would produce a day which is 3.5m

Using this expression we can determine how many pounds of trash a family of 4 would produce which is {{{3.5(4)=14}}}

Therefore a family of four will produce 14 pounds of trash each day.
