Answer explanation

You are buying both corn and rice to make chicken feed. Rice is $2 per bag, and corn costs $3 per bag. You have $24 to spend. Select ALL the coordinate points that represent possibilities for the number of bags of corn and rice you can buy.

• (2, 1)

• (2, 0)

• (4, 5)

• (7, 3.5)
