Solution
- If the number of $100 notes is x.
- We are told that there are 3 times as many $50 notes as $100 notes. This means that if there are x $100 notes, then,
[tex]\text{ There are }3x\text{ \$50 notes}[/tex]- Also, we are told that there are 6 times as many $20 notes as $50 notes. This implies that
[tex]\text{ There are }6(3x)=18x\text{ \$20 notes}[/tex]- The total amount in the safe is $1,525,000. Thus, it means that if we take all the $100, $50, and $20 notes, they add up to $1,525,000.
- Thus, we have that:
