My question is: 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? Your thoughts:
Mrs. Brown has a $125 x 10 / 100 = $12.5 discount for her purchase. So, the remaining amount she needs to pay is $125 - $12.5 = $112.5. But Mrs. Brown can still avail of the 5% discount, so she has an additional discount of $112.5 x 4 / 100 = $4.5. Therefore, Mrs. brown will only pay $112.5 - $4.5 = $108. The final answer: 108.
