Answer:
9 more muffins
Explanation:
Lucinda has 9 ounces of flour.
To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:
(1/3)x = 9 where x is the number of cupcakes.
Therefore, x = 9 × 3 = 27 cupcakes
To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:
(1/4)y = 9 where y is the number of muffins.
Therefore, y = 9 × 4 = 36 muffins
The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins
