Match each real world situation to its equation

• You want to earn $1000 this summer

  teaching swim lessons. You can earn

  $10 per hour for individuals and $25 per

  hour for groups. Let x represent, hours of individual lessons

  and y represent, hours of

  group lessons

• A mountain hiker has been hiking for 25 minutes and is at an elevation of 1000 feet. As they descend the mountain, their elevation drops by 10 feet per minute.
  Let x be the number of minutes hiked, and y be the elevation in feet.

• A freelance designer charges $1000 for the initial setup and then $25 per hour. Let x be the number of hours worked, and y be the total charge.

• You are selling T-shirts for $25 each to raise $1000. Let x be the number of T-shirts sold, and y be the remaining money needed to reach $1000.

• An electrician charges a base fee of $25 and plus $10 for each day of work. Let x, represent the number of hours and y represent his profit.
