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.
