Write and solve an inequality to determine how many pledges each of the 15 students in your class needs to collect in order to meet the seventh-grade goal of at least 250 pledges, given that the other classes have already collected a total of 130 pledges.

Final answer:

To meet the seventh-grade goal of at least 250 pledges with 130 already collected by other classes, each of the 15 students in your class must collect at least 8 pledges.

Step-by-step explanation:

To determine how many pledges each of the 15 students needs to collect to meet the seventh-grade goal of at least 250 pledges, given that other classes have already collected a total of 130 pledges, we need to set up and solve an inequality. The total number of pledges needed from your class can be calculated by subtracting the number of pledges already collected by other classes from the total goal. This gives:

250 (total goal) - 130 (pledges collected) = 120 (pledges needed from your class)

Let x represent the number of pledges each of the 15 students needs to collect. Then the inequality can be written as:

15x ≥ 120

Dividing both sides of the inequality by 15, we get:

x ≥ 8

So, each student needs to collect at least 8 pledges to meet the seventh-grade goal.
