<human>:  Leah earned $28 working odd jobs around the neighborhood. She spent a seventh of it on a milkshake and put half of the rest in her savings account. She left the remaining money in her wallet. Her dog got ahold of her wallet and shredded all the money inside but $1. How many dollars did Leah lose?
<bot>: How much did Leah spend on a milkshake? ** Leah spent 28 / 7 = $<<28/7=4>>4 on a milkshake.
How much money did Leah have left? ** She had 28 - 4 = $<<28-4=24>>24 left.
How much money did Leah have in her wallet? ** She put half in her savings account and half in her wallet, so she had 24 / 2 = $<<24/2=12>>12 in her wallet.
How many dollars did Leah lose? ** Her dog shredded all the money in her wallet but $1, so Leah lost 12 - 1 = $<<12-1=11>>11.
