                            Lorelai is making Christmas Cookies for her friends. Each cookie batch makes 50 cookies and she wants to package 3 cookies to each person. if she wants to make 75 packages, how many full BATCHES (round up) does she need to bake. 
                            What is 5
75 (packages)  x 3(cookies in each package) = 225 (total number of cookies needed)
225(total number of cookies) / 50 (number of cookies in each batch = 4.5 so she need 5 full batches
