So since we know that 1 bag of roses and daffodils cost $12, we can subtract that from $28. Then we get left with $16 for 2 bags of daffodils since we subtracted $12 that was for 1 bag of roses and 1 bag of daffodils. Then we divide the $16 by 2 because there are 2 bags of daffodils left. That would give us $8 meaning that each bag of daffodils cost $8. Then we subtract the $8 from $12 and get $4. That would mean a bag of roses costs $4 and a bag of daffodils cost $8.
