Jonathan and members of his Spanish Club are going to Costa Rica. He purchases 10 traveler's checks in denominations of $20, and $100, totaling $370. He has twice as many $20 checks as $50 checks. How many of each denomination does he have?

Let the no. of $50 checks be x
then the no. of $20 checks would be 2x
and the no. of $100 checks would be 10-x-2x=10-3x
Total amount being $370 we can write
So denomination is as follows
The no. of $50 checks =
The no. of $20 checks
The no. of $100 checks
