Answer the following question.
Carla's teacher tells her that she needs to collect 30 leaves and 20 bugs for a project that's due in 10 days. How many items does Carla need to collect each day if she always wants to collect the same daily amount?
Step-by-step reasoning process: First find the total number of items Carla needs to find by adding the number of leaves to the number of bugs: 30 leaves + 20 bugs = 50 items. Now divide the total number of items by the number of days Carla has to do her assignment to find the daily collection amount: 50 items / 10 days = 5 items / day.
The answer is 5.

Answer the following question.

Step-by-step reasoning process: Matt used 4 * 5 = 20 pounds of flour. That means he made 20 / 2 = 10 batches. So he cooked 10 * 12 = 120 cookies. After Jim eats 15 there are 120 - 15 = 105 cookies left.
The answer is 105.
