Write a system of linear inequalities for this situation. Graph the inequalities. You can spend at most $21 on fruit. Blueberries cost $4 per pound and strawberries cost $3 per pound. You need at least 3 pounds to make muffins. Is it possible to buy 4 pound of blueberries and 1 pound of strawberries in this situation?
What is
x = pounds of blueberries x + y > 3 (or equal to) y = pounds of strawberries 4x + 3y < 21 ( or equal to) Yes this is more than 3 pounds and costs $19, which is less than $21.

You can spend at most $60 on lace. Cotton lace is $2 per yard and linen lace is $3 per yard. Write an inequality for the amounts of lace you can buy. Can you buy 12 yards of cotton lace and 15 yards of linen lace? Explain
What is
2x + 3y < 60 (or equal to) No you cannot buy 12 yards of cotton lace and 15 yards of linen lace because (12, 15) is not a solution of the inequality.
