Annie went to the bakery to buy cookies for the tea party the cookies she wanted cost $1.20 per 1/2 dozen $2.38 per dozen or $0.23 each cookies how much less would it cost to buy 1/2 dozen plus three cookies then it would to buy one dozen cookies

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
