Kahidja initially baked 5 dozen cookies. Since one dozen equals 12, we can calculate the total number of cookies she baked:
5 dozen = 5 x 12 = 60 cookies.
After baking, she gave 24 cookies to a friend. To find out how many cookies she has left, we simply subtract the number of cookies given away from the total she baked:
60 cookies – 24 cookies = 36 cookies.
So, after giving 24 cookies to her friend, Kahidja has 36 cookies left.
