Aling Azon has 80.00 in coins in her purse. If there are twice as many 5 .00 coins as 10.00 coins. How many of each kind are in the purse ?

Sagot :

x = no. of 10 peso coins
10x = total value of the no. of 10 peso coins

2x = no. of 5 peso coins
5 (2x) or 10x = total value of 5 peso coins

10x + 10x = 80
20x = 80
20x(1/20) = 80 (1/20)
20/20x = 80/20
1x = 80/20
x = 4

x = 4 = no. of 10 peso coins
2x = 2 x 4 = 8 = no. of 5 peso coins

Therefore, the answer is:

There are 4 ten peso coins and 8 five peso coins.
