A book 2

A book priced at USD25 is sold at a 30% discount at a bookstore. If the same book is sold online for USD20, buyers are given a 15% discount. Applying the concept of proportion, determine the better option for purchasing the book. Justify your choice. Write the result as 1 or 2 (1=bookstore, 2=online).

Correct answer:

x = 2

Step-by-step explanation:

a=25 USD r1=100%30%=110030=0.7 b=20 USD r2=100%15%=110015=0.85  p1=r1 a=0.7 25=235=1721=17.5 USD p2=r2 b=0.85 20=17 USD  p2<p1  x=2
