Answer:
The Smith generates 6 bags of trash per month, and the Joneses generates 6 bags of trash per month.
Step-by-step explanation:
We know that
- The Smith generates one and a half times trash as much as the Joneses.
- Both families generate 15 bags of trash per month.
To solve this problem, we need to transform each statement in a equation.
[tex]S=1\frac{1}{2}J[/tex]
Where [tex]S[/tex] represents the Smith, and [tex]J[/tex] represents the Joneses.
This expressions expresses the one and a half difference between the two families.
If both families produce 15 bags of trash, the equation would be
[tex]S+J=15[/tex]
Now, we replace the first equation into the second one and solve for [tex]J[/tex]
[tex]1\frac{1}{2}J+J=15\\1.5J+J=15\\2.5J=15\\J=\frac{15}{2.5}=6[/tex]
Then, we replace this value into one equation to find the other variable
[tex]S+J=15\\S+6=15\\S=15-6\\S=9[/tex]
Therefore, the Smith generates 6 bags of trash per month, and the Joneses generates 6 bags of trash per month.
