Aroast chicken with a base price of $6.89 is marked up by 21%. what is the new price, to the nearest cent? a. $12.33 b. $9.97 c. $8.34 d. $7.10

Option C is correct.

Step-by-step explanation:

Base Price of a roast chicken = $ 6.89

Increase in Price = 21 %

So,

New Price = Base price + Increased amount

                 =  6.89 + 21 % of 6.89

                 =  

                 =  

                 =  6.89 + 1.4469

                 =  8.3369

                 =  $ 8.34 (to nearest cent)

Therefore, Option C is correct.

a = 11 : 4

b = 38

c = 1 for every 6
