David is organizing a charity walkathon. He is collecting pledges from participants, and each participant has promised to donate $12. If David raises a total of $360, how many participants made pledges?

1 answer

To find out how many participants made pledges, we can use the following formula:

Total Amount Raised=Number of Participants×Amount Pledged by Each Participant

From the problem, we know:

  • Total Amount Raised = $360
  • Amount Pledged by Each Participant = $12

Let x be the number of participants. We can set up the equation:

360=x×12

To solve for x, we can divide both sides of the equation by 12:

x=36012

Calculating the right side:

x=30

Therefore, the number of participants that made pledges is 30.
