Each package of dog treats has 13 treats.
The equation d = 13t, where d represents the total number of dog treats and t represents number of packages, shows this relationship.
If Esther bought 39 dog treats total, how many packages did she buy?
We can use the equation d = 13t to solve the problem.
Given that Esther bought 39 dog treats, we can substitute d = 39 into the equation:
39 = 13t
To solve for t, we can divide both sides by 13:
t = 39/13
Simplifying, we get:
t = 3
Therefore, Esther bought 3 packages of dog treats.
