Respuesta :
She keeps 60 cookies. First, add the total amount of cookies she baked. Since there are 12 to a dozen, you will find that she baked 108 cookies. Then, subtract 48, because she gave away a total of 4 dozen cookies (2.5dozen+1.5dozen=4 dozen). When 48 is subtracted from 108, you are left with a total of 60.
