Christine earns dollars each week working part-time at a bookstore. She earns one additional dollar for each book that she sells. Let be the amount (in dollars) that Christine earns in a week if she sells books. Write an equation relating to . Then use this equation to find the amount of money Christine earns if she sells books.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

60%
