Astore which formerly sold peppers at 3 pounds for $2.00 changed the price to 2 pounds for $1.50. if x is the percent increase in the price per pound x=

a)25%

b)20%

c)16 2/3%

d)12 1/2%

D 12½%

Step-by-step explanation:

∆=1.5/2-2/3

=4.5/6-4/6

=0.5/6

∆=0.083 $/lb

X=∆/(original price)•100

=0.083/(2/3)•100

=0.1245•100

X=12.45%

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 %
