Question

There are 32 bills inside a wallet, divided between Php 20.00 bills and Php 200.00 bills. The bills amount to a total of Php 2,080.00. How many of each bills are in the wallet?

Answer 1

Define x :

Let the number of Php 20 bills be x

the number of php 200 bills = 32 - x

Solve x:

20x + 200(32 - x) = 2080

20x + 6400 - 200x = 2080

180x = 4320

x = 4320 ÷ 180

x = 24

Find the number of notes of each type:

Php 20 bills = x = 24 pieces

Php 200 bills = 32 - x = 32 - 24 = 8 pieces

Answer: There are 24 pieces of Php 20 bills and 8 pieces of Php 200 bills.
