Jayee's piggy bank contains 70 coins, in 25 centavo and 5 peso coins. the total amount of the coins is 160 pesos. how many of each kind were there?
--------------
1 peso = 100 centavos
5 peso = 500 centavos
-----------------------------
Equations:
Quantity: c + p = 70 coins
Value::: 25c+500p = 16000 centavos
---------------------------
Modify:
25c + 25p = 25*70
25c+ 500p = 16000
---
Subtract and solve for "p":
475p = 14250
p = 30 (# of 5 peso coins)
---
Solve for "c":
c + p = 70
c = 40 (# of 25 centavo coins)
