Sunflower seeds cost $4.50 per bag. You want to spend less than $30. Write a system of inequalities for this situation. Graph the inequalities, and find 2 ways you could divide your money.
Answer provided by our tutors
let
o = the number of Oyster Grit bags
s = the number of Sunflower seeds
you want to buy at most 6 bags
o + s <= 6
you want to spend less than $30
4*o + 4.50*s < 30
the system of inequalities is
o + s <= 6
4*o + 4.50*s < 30

One way to divide the money is to buy 3 bags Osyter Grit and 2 bags Sunflowers seeds that is divide the money
3*4 = $12 for 3 bags of Oyster Grit
2*4.5 = $9 for 2 bags of Sunflower seeds
Second way to divide the money is to buy 4 bags Osyter Grit and 2 bags Sunflowers seeds that is divide the money
4*4 = $16 for 4 bags of Oyster Grit
2*4.5 = $9 for 2 bags of Sunflower seeds
