Answer Key/Rubric
- $0.15 or 15¢
- $0.19 or 19¢
- $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
- $1.80 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
- Several variations possible.
Best combination would be two dollar bills, one dime and one nickel, because that is the least amount of currency.
