Verified Answer
Jane wants to purchase a history book and a literature book that are s...
Given:
  • Regular Book Shop
    • Price of History book = $20
    • Price of Literature book = $30
  • Online used-book store
    • Discount on History book = 20%
    • Discount on Literature book = 30%
    • Additional discount = 10% of (Discounted Price of History Book + Discounted Price of Literature Book)
      • Note that this additional discount applies since Jane bought 2 books
    • Shipping charges = $2.7
To Find: % Savings of Jane by buying the 2 books from online used-book store.
Approach:
    • So, to answer the question, we need to know ‘amount paid at used
      book store’ and ‘amount paid at regular book shop’
  1. (Amount paid at used-book store) = (Discounted Price of History Book + Discounted Price of Literature Book) – (Additional Discount) + (Shipping Charges)
  2. (Amount paid at regular book shop) = (Price of History Book) + (Price of Literature Book)
Working out:
  • Finding Amount paid at used-book store
    • Discount on History Book = 20% of 20 = 4
      • So, Discounted price of History book = 20 - 4 = $16
    • Discount on Literature book = 30% of 30 = 9
      • So, Discounted price of Literature book = 70% of 30 = $21
    • Discounted Price of History Book + Discounted Price of Literature Book = $16 + $21= $37
    • So, additional discount = 10% of $37 = $3.7
    • So, (Amount paid at used-book store) = $37 - $3.7 + $2.7 = $36
  • Finding Amount paid at regular book shop
    • (Amount paid at regular book shop) = $20+ $30 = $50
Looking at the answer choices, we see that the correct answer is Option A
