Answer:
[tex]m\approx 2.62[/tex] dollars
Step-by-step explanation:
Let us represent the cost of the milk with [tex]m[/tex], since it is what the word starts with, after all.
We know that the fabric softener is three times as much as the milk, so we can represent that with [tex]3m[/tex]. Similarly, we can replace the other two variables based on their correlation to milk in the problem. We would need to sum up all three of them afterward, which would be:
[tex]\frac{1}{5}m + 3m + m = 11\\ 4\frac{1}{5}m = 11[/tex]
Now that we have a simplified set of equations, we can isolate our variable and solve:
[tex]4\frac{1}{5}m = 11\\ m = 11\div 4\frac{1}{5}\approx 2.62[/tex]
So, the milk price would be around [tex]2.62[/tex] dollars.
I hope this helps!
