ROPES #1 Park A state park charges admission of $6 per person plus $3 for parking. She was exciting about seeing the 22 alligators that were at the park. Jo paid $27 when her car entered the park. Write and solve an equation to find the number of people in Jo’s car. Be sure to explain what your variable represents.

ROPES #2 Rectangle The width of a rectangle is 6 cm less than the length. The perimeter is 72 cm. Write and solve an equation to find the width and the length of the rectangle.

ROPES #3 Age Jan is one year younger than her brother Bill and one year older than her sister Sue. Jan, Bill and Sue all have brown eyes and green hair. The sum of the ages is 57. How old is each family member?
