<human>:  It's Mother's day, so mothers get a 10% discount on the department store. Mothers who have 3 children or more can get an additional 4% off the discounted price. If Mrs. Brown has 4 children and wants to buy a pair of shoes that costs $125, how much will she pay?
<bot>: How much is the discount? ** Mrs. Brown has a $125 x 10/100 = $<<125*10/100=12.5>>12.5 discount for her purchase.
How much does she need to pay? ** So, the remaining amount she needs to pay is $125 - $12.5 =$<<125-12.5=112.5>>112.5.
How much is the additional discount? ** But Mrs. Brown can still avail of the 5% discount, so she has an additional discount of $112.5 x 4/100 = $<<112.5*4/100=4.5>>4.5.
How much will she pay? ** Therefore, Mrs. brown will only pay $112.5 - $4.5 = $<<112.5-4.5=108>>108.
