The total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
<h3>
Number of container</h3>
1 cup of rubbing alcohol:
1 cup of rubbing alcohol=1÷1/2
1 cup of rubbing alcohol=2
Cup of alcohol needed:
Cup of alcohol needed=1+1/2+16
Cup of alcohol needed=17.5 cups
Total cups:
Total cups=17.5×2
Total cups=35 cups
Number of container:
Number of container=1+35/5
Number of container=1+5
Number of container=6 containers
Therefore the total solution will include 17.5 cup of vinegar 0.5 cups of rubbing alcohol, and 2 cup of water which is a total of 35 cups of solution. Sofie will need 6 total containers to hold all of the solution.
