Answer:
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.
