1. You are participating in a fundraiser in which you do yard work for donations. People can

donate money based on a flat fee or based on the number of hours you work. So far, you
have two donors. Your teacher has agreed to donate $10 and your brother has agreed to
donate $2.25 per hour. If together they donated $39.25, write the equation that represents
this situation, then solve.

Answer:

  • 13 hours

Explanation:

Given:

  • One time donation = $10
  • Hourly donation = $2.25
  • Total donation = $39.25
  • Number of hours = x

Required equation:

  • 10 + 2.25x = 39.25

Solve for x:

  • 2.25x = 39.25 - 10
  • 2.25x = 29.25
  • x = 29.25/2.25
  • x = 13
