Answer:
4 times
Step-by-step explanation:
1 quart is equivalent to 32 fluid ounces.
If each eruption consumes 8 fluid ounces of vinegar. Assuming that the amount of vinegar required per eruption is constant, the number of times Tanvi can make her volcano erupt is:
[tex]n=\frac{32}{8}\\n=4\ times[/tex]
Tanvi can make her volcano erupt 4 times with 1 quart of vinegar.
