A farmer sells apples for $2 each and oranges for $3 each. If he wants to make at least $60, write the inequality in standard form and graph it. How many apples and oranges can he sell to meet his goal?

• The farmer can sell any combination of apples and oranges that satisfies the inequality 2x + 3y ≥ 60, such as (30, 0), (0, 20), or (15, 10).

• The inequality is 2x + 3y ≤ 60.

• Selling 10 apples and 15 oranges does not meet the goal.

• The farmer can only sell 20 apples and 0 oranges.

A bakery sells cupcakes for $3 each and cookies for $2 each. If they want to make at least $100, write the inequality in standard form and graph it. What combinations of cupcakes and cookies can they sell?

• The combinations must include at least 50 cookies.

• The inequality is 3x + 2y ≥ 100, and the combinations of cupcakes (x) and cookies (y) can be any non-negative integers that satisfy this inequality.

• The inequality is 2x + 3y ≤ 100

• The inequality is 4x + y ≥ 100

A pizza shop sells large pizzas for $12 and small pizzas for $8. If they want to make at least $150, write the inequality in standard form and graph it. How many large and small pizzas can they sell?

• The inequality is 12x + 8y = 150.

• They can only sell small pizzas to meet the goal.

• The inequality in standard form is 8x + 12y ≤ 150.

• The inequality in standard form is 12x + 8y ≥ 150. Possible combinations of large and small pizzas can be found by solving this inequality.
