A 4-pound bag of grass seed costs $20. A 12-pound bag of grass seed costs $36.
How much less does each pound of grass seed cost if a customer buys a 12-pound bag?
To find out how much less each pound of grass seed costs when a customer buys a 12-pound bag instead of a 4-pound bag, we first need to calculate the cost per pound for each option.
For the 4-pound bag: $20 / 4 pounds = $5 per pound.
For the 12-pound bag: $36 / 12 pounds = $3 per pound.
The difference between the two is $5 - $3 = $2.
Therefore, each pound of grass seed costs $2 less if a customer buys a 12-pound bag instead of a 4-pound bag.
