Question

A cash box of $1 and $5 bills is worth $45. The number of $1 bills is three more than the number of $5 bills. How many of each bill does it contain?

Answer 1

Answer:

$5: 7

$1: 10

Step-by-step explanation:

We can write the equation as such.

1. 5x + (x + 3) = 45

2. 6x = 42

3. x = 7

The number of $5 bills is 7, now we can use the x + 3 to solve the amount of $1 bills.

1. x + 3 = ?

2. 7 + 3 = 10

There are 10 $1 bills.
