  2.   At the annual Fall Festival, Jamal wants to rent a canoe for a trip down the Kaskaskia River. A boat shop in town rents canoes for $10 plus $3 per hour. Write a rule for calculating the cost for renting the canoe. Use h to represent the number of hours the canoe is in use and c to represent the cost.

  3.   In a basketball game, the number of points scored for a team consists of two-point field goals, three-point field goals, and (one-point) free throws. If x represents two-point field goals, y represents three-point field goals, z represents free throws, and p represents the total number of points, write a rule for calculating the total points scored in the game.
    A. p = x + 2y + 3z B. p = 2x – 3yz
    C. p = 2x + 3yz D. p = 2x + 3y + z
    Hint

  4.   Luis is l inches tall. Taylor is 10 inches shorter than Luis. Isabel is as tall as Luis. Alexa is 6 inches taller than Isabel. Using l, t, i, and a for the heights of Luis, Taylor, Isabel, and Alexa respectively, which rule does not describe one of the situations above?
    A. a = 6 + i B. i = l
    C. l = 6a + t D. t = l – 10
    Hint
