Answer:
Each tube came with 0.54 ounces of glue.
Explanation:
We know that she bought 3 tubes of glue.
The amount of glue in this 3 tubes is equal to the amount she used (0.27 ounce) and the total amount that is left (1.35 ounces).
If we assumed that the 3 tubes came with the same amount of glue, we can calculate this volume by dividing the total amount of glue by 3 (the amount of tubes).
Each tube came with 0.54 ounces of glue.
