Answer:
It would cost $0.49 less
Step-by-step explanation:
If Annie buy 1/2 dozen it would cost her $1.20
and 3 cookies would be $0.23 × 3 = $0.69
And totally it would be $1.20 + $0.69 = $1.89
And to buy a dozen would cost $2.38, so
to buy 1/2 dozen and 3 cookies would cost $2.38 - $1.89 = 0.49 lesser than buying a dozen
