To find out how much change is left for each person, we need to subtract the cost of the item they want to buy from the amount of money they have.
Here is the step-by-step calculation for each person:
1. Gary
*
Money Gary has: He has one $1 bill and two quarters (25 cents each).
* $1.00 + $0.25 + $0.25 =
$1.50
*
Cost of donut: $1.27
*
Change: $1.50 - $1.27 =
$0.23
2. Deborah
*
Money Deborah has: She has two $1 bills and four dimes (10 cents each).
* $1.00 + $1.00 = $2.00
* 4 dimes = $0.40
* Total:
$2.40
*
Cost of flower: $2.14
*
Change: $2.40 - $2.14 =
$0.26
3. Jason
*
Money Jason has: He has two $1 bills and one dime (10 cents).
* $1.00 + $1.00 = $2.00
* Total:
$2.10
*
Cost of toy duck: $2.19
*
Change: Since $2.10 is less than $2.19, Jason does not have enough money.
* Calculation: $2.10 - $2.19 =
-$0.09 (He needs 9 cents more).
4. Sarah
*
Money Sarah has: She has two $1 bills and five nickels (5 cents each).
* $1.00 + $1.00 = $2.00
* 5 nickels = $0.25
* Total:
$2.25
*
Cost of donut: $2.55
*
Change: Since $2.25 is less than $2.55, Sarah does not have enough money.
* Calculation: $2.25 - $2.55 =
-$0.30 (She needs 30 cents more).
Final Answer:
Gary's change: $0.23
Deborah's change: $0.26
Jason's change: -$0.09 (Not enough money)
Sarah's change: -$0.30 (Not enough money)
