<human>:  Jen bought a bag of cookies and ate three-quarters of the bag that day. The next day, she ate half of the remaining cookies. She has 8 cookies left on the third day. How many cookies were in the bag to start?
<bot>: How many cookies did Jen have on the second day? ** On the third day, Jen had half of the second day’s cookies left, so on the second day, she had 8 * 2 = <<8*2=16>>16 cookies.
How many cookies were in the bag to start? ** On the second day, she had 1/4 of the first day’s cookies left, so she started with 16 * 4 = <<16*4=64>>64 cookies in the bag.
