Question

When the first Harry Potter movie came out, "The Sorcerer's Stone," a local book store marked all the Harry Potter books up by 40.5%. If "The Sorcerer's Stone" paperback cost $7.37 before the movie came out, how much did it cost after the mark up? (1 pt) *

Answer 1

Answer:  fina price = 10.35

Step-by-step explanation:

increase in price :40.5%

initial cost: $7.37

increased price = 40.5% (7.37)

                          =$\frac{40.5}{100} (7.37)$

= 0.405 * (7.37)

=  2.98485 = 2.98

thus

final price  = initial pirce + increased price

=7.37+2.98

=10.35

thus price after mark up : $10.35
