Answer Key/Rubric

  1. $0.15 or 15¢

  2. $0.19 or 19¢
  1. $1.10 in change; many combinations possible
    One example:  one-dollar bill and one dime
    Acceptable work may include, but is not limited to:
  • Find total of soda and granola bar:
    $2.85 + $1.05 = $3.90
  • Subtract to find the change he will get back:
    $5.00 - $3.90 = $1.10
  1. $1.80 back; many combinations possible.
    One example combination:  1-dollar bill, 3-quarters, and 1-nickel
    Acceptable work may include, but is not limited to:
  • Find how much the candy costs
    $0.25 x 7 = $1.75
  • Find the total for the candy and gum
    $1.75 + $1.45 = $3.20
  • Subtract candy total from $5
    $5.00 - $3.20 = $1.80
  1. Several variations possible.
    Best combination would be two dollar bills, one dime and one nickel, because that is the least amount of currency.
