Answer:
27 cookies
Explanation:
We Know
Each batch makes 24 cookies.
Ralph makes 2 1/2 batches of oatmeal cookies.
2.5 x 24 = 60 cookies
Ralph gives away 1/4 of his cookies to his class at school.
60 - (60 x 1/4) = 45 cookies he has left
2/5 of his remaining cookies to his bus driver.
45 - (45 x 2/5) = 27 cookies
So, Ralph has 27 cookies left.
