jessi worrks at a animal shelter the shelter needs at least 600 servings of canned cat food for one week wil the shelter have enough servings of cat foods for one week id jessi order 12 more cases

It depends on how many servings are in each case of canned cat food. If each case contains 50 servings, which would equate to 600 servings for 12 cases, and the shelter needs at least 600 servings for one week, then the shelter would have just enough servings for one week. However, if each case contains fewer than 50 servings, then Jessi would need to order the 12 additional cases to ensure there is enough food for the week.
