Question

Sandy brought 64 dozen cookies to the bake sale. Alejandro brought

dozen fewer cookies than Sandy brought. Pierre brought 2 dozen
fewer cookies than Alejandro brought. How many dozen cookies
did Pierre bring?

Answer 1

Sandy - 64 dozens = 768 single cookies.
Alejandro - 62 dozens = 744 single cookies.
Pierre - 60 dozens = 720 single cookies.

Pierre brought 720 cookies. You solve this by understanding that one dozen = 12 and multiplying 12 by the given number of dozens each student brought to find out the exact amount of single cookies. Hope this helped !
