"Andy has 30 coins made up of quarters and half dollars" means that q%2Bh=30 where 'q' is the number of quarters and 'h' is the number of half dollars.

Also, since "their total value is $12.25", this means that 0.25q%2B0.5h=12.25 (note: 0.25q is the total amount of money in terms of quarters only and 0.5h is the total amount of money in terms of half dollars only)
