A school class is selling cookies for a fundraiser. The class has made 120 cookies to sell, and the supplies to make the cookies cost $22. The class wants to make at least $50 from selling cookies.

Which inequality should be used to determine the possible prices (p) the class can sell the cookies for to reach its goal?

120p−22<50
120p−22<50

120p−22≤50
120 p minus 22 is less than or equal to 50

120p−22>50
120 p minus 22 is greater than 50

120p−22≥50
120 p minus 22 is greater than or equal to 50

To determine the possible prices (p) that the class can sell the cookies for to reach its goal of making at least $50 after covering the costs, we can set up the following inequality:

  1. The total revenue from selling the cookies is given by \( 120p \) (where \( p \) is the price per cookie).
  2. The total cost to make the cookies is $22.
  3. The class wants to make at least $50 after covering the cost, so we need to express this condition mathematically.

To make at least $50 after the costs, we set up the inequality:

\[ 120p - 22 \geq 50 \]

This means:

  • Total revenue (120p) minus total costs ($22) should be greater than or equal to $50.

Thus, the correct option is:

120p - 22 ≥ 50

For Question 2, to find the price per cookie when they want to make at least $50, we can solve the inequality:

  1. Start with \( 120p - 22 ≥ 50 \).
  2. Add 22 to both sides: \( 120p ≥ 72 \).
  3. Divide by 120: \( p ≥ 0.60 \).

Therefore, the class should sell each cookie for at least $0.60 to reach their goal.
