Question

a wallet that holds $25 contains the same number of $1 bills, $5 bills, and quarters. how many of each type of bill or coin does the wallet contain?

Answer 1

Ok so you know that since it is a whole number the number of quarters has to add to equal a whole number so start with 4
4 quarters = $1
4 dollars = $4
4 five $5 = $20
So 20+4+1 = 25
There for the answer is 4

Answer 2

The number of each type of bill or coin the wallet contains is:

4

Explanation:

It is given that:

A wallet holds $ 25 in total.

Also, the number of $ 1 bills,$ 5 bills and qaurters are present in equal number in the wallet.

Let the number of each coin or bill in the wallet be: x

Also, we know that:

1 quarter= 1/4 dollar

i.e.

1 quarter= 0.25 dollar

Hence, we get:

x+5x+0.25x=25

i.e.

6.25 x=25

On dividing both side of the equation by 6.25 we get:

x=25/6.25

i.e.

x=4

Hence, the number of each kind of coin or bill are: 4
