A 4 pound bag of grass seed cost $20 a 12 pound bag of grass seed cost $36 how much land does each kind of grass seed cost if a customer buys a 12 pound bag

To find out how much land each kind of grass seed covers per pound, we need to determine the cost per pound for each bag of grass seed.

For the 4 pound bag:
Cost per pound = $20 / 4 pounds = $5 per pound

For the 12 pound bag:
Cost per pound = $36 / 12 pounds = $3 per pound

So, if a customer buys a 12 pound bag of grass seed, it would cost $3 per pound.
