<human>:  Matt can make a batch of a dozen cookies using 2 pounds of flour. He uses 4 bags of flour each weighing 5 pounds. If Jim eats 15 cookies how many cookies are left?
<bot>: How many pounds of flour did Matt use? ** Matt used 4*5=<<4*5=20>>20 pounds of flour
How many batches did Matt make? ** That means he made 20/2=<<20/2=10>>10 batches
How many cookies did Matt cook? ** So he cooked 10*12=<<10*12=120>>120 cookies
How many cookies are left? ** After Jim eats 15 there are 120-15=<<120-15=105>>105 cookies left
