Mark uses 1 pt 9 fl oz and then 2 pt 10 fl oz from a container of film
developer that holds 3 qt. How much of the developer remains?
How would I set this problem up?
Find out how many pints are in 3 qts.
Find out how many oz are in a pint.
Then you can figure out how much was used and, as a result, how much was left.
To set up this problem, we need to convert the measurements to the same units.
First, let's find out how many pints are in 3 quarts.
We know that there are 2 pints in 1 quart. So we can multiply 3 quarts by 2 pints/quart:
3 quarts * 2 pints/quart = 6 pints
Next, let's find out how many fluid ounces are in a pint.
We know that there are 16 fluid ounces in 1 pint. So we can multiply the number of pints from the previous step by 16 fluid ounces/pint:
6 pints * 16 fluid ounces/pint = 96 fluid ounces
Now, we can calculate how much was used. Mark used 1 pint 9 fluid ounces and then 2 pints 10 fluid ounces:
1 pint 9 fluid ounces + 2 pints 10 fluid ounces = 3 pints 19 fluid ounces
Finally, we subtract the amount used from the total amount to find out how much remains:
96 fluid ounces - 3 pints 19 fluid ounces
To subtract mixed units, we first need to convert the pints to fluid ounces.
We know that 1 pint = 16 fluid ounces, so we can multiply 3 pints by 16 fluid ounces/pint:
3 pints * 16 fluid ounces/pint = 48 fluid ounces
Now, we can subtract the remaining fluid ounces from the total amount:
96 fluid ounces - 48 fluid ounces = 48 fluid ounces
Therefore, there are 48 fluid ounces of film developer remaining in the container.
