Amy baby sat from 7: 30 to 11: 00 p. m. if amy was paid $15.75, how much did she earn per hour

$4.50 per hour.

She worked 3 and a half hours. So since her total is $15.75 you'd divide that by 3.5, which works out to $4.50.

Hope this helps! :)  

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 %
