Nope.

First, add the amount used -- 1 pt. 9oz + 2 pt. 10 oz. How many pints and ounces is that?

Then, subtract that amount from 3 quarts.
Answered by Ms. Teri
3 pint and 19 oz
Answered by Ms. Sue
That's a good start -- that's the amount of developer he used.

Next -- 3 pt., 19 oz. to 4 pt, 3 oz.

Subtract: 3 qt. - 4 pt. 3 oz = ?

Hint: 3 qt = 6 pints = 5 pints, 16 oz.
