#1/2# cup = 24 teaspoons.

1 bag of sugar = 227 teaspoons.

#227/24 = 9##11/24#, so you can
bake 9 complete batches of muffins.

You can make #9# whole batches of muffins.

The sugar for each batch costs about #$0.28#

Explanation:

Presuming that each batch of muffins uses #(1)/(2)# cup of sugar

Find the number of teaspoons used in each batch

1 cup of sugar = 48 tsp
Therefore, 1/2 cup of sugar = 24 tsp

So 24 tsp are used for each batch of muffins

Find the number of batches (each using 24 tsp) that can be made with 227 tsp

#227 -: 24 = 9  "batches"#

Answer:
You can make #9# whole batches of muffins.

There will be #11# teaspoons left over.
