Tim bought a book that was marked down to 50% of its original price. He used a coupon to save an additional 40% off of the sale price. If the book’s original price was $12.00, what was the final price Tim paid?

A. $1.20

B. $2.40

C. $3.60

D. $5.60

Answer:Original price of book= $12.00

Price after 50% mark down= 50/100*12

= $6.00

Price after using 40% coupon= 40/100*6

=$2.4

Hence the final price is $2.40

Answer:$2.40

Step-by-step explanation:50% of 12 is 6, and 40% of 6 is 2.40
