Indigo finds some dimes and quarters in her piggy bank. How much money in dollars) does she have if she has 12 dimes and 5 quarters? How much money in
dollars) does she have if she has z dimes and y quarters?
Total value, 12 dimes and 5 quarters (dollars):
Total value, x dimes and y quarters (dollars):

1) $2.45

2) $(0.25y + 0.1z)

Step-by-step explanation:

dimes are 0.10 in value, quarters are 0.25

1) How much money in dollars does she have if she has 12 dimes and 5 quarters? 12(0.1) + 5(0.25) = 1.2 + 1.25 = $2.45

2) How much money in dollars does she have if she has z dimes and y quarters?

z(0.10) + y(0.25)= 0.25y + 0.1z

I rearranged it because we put variables in alphabetical order.

LMK if you have questions.

step-by-step explanation:

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 %
