Here are the solutions to the word problems, showing the work step-by-step.
1. Howard's Book
*
Step 1: Calculate how much Howard paid.
* $5 bill = $5.00
* 2 toonies ($2 each) = $4.00
* 1 loonie ($1) = $1.00
* Total Paid: $5 + $4 + $1 =
$10.00
*
Step 2: Calculate the change.
* $10.00 (Paid) - $8.79 (Cost) =
$1.21
*
Step 3: Show the coins/bills for the change.
To make $1.21, the clerk could give:
*
1 Loonie ($1.00)
*
2 Dimes ($0.20)
*
1 Penny ($0.01)
2. Sarah's Stickers
*
Step 1: Calculate how much Sarah paid.
* 2 toonies ($2 each) =
$4.00
*
Step 2: Calculate the change.
* $4.00 (Paid) - $2.49 (Cost) =
$1.51
*
Step 3: Draw/Show the money.
To make $1.51, you would draw or list:
*
1 Loonie ($1.00)
*
2 Quarters ($0.50)
*
1 Penny ($0.01)
3. Billy's Lunch
*
Step 1: Calculate the total change needed.
* $5.00 (Paid) - $3.10 (Cost) =
$1.90
*
Step 2: Show 2 different ways to make $1.90.
*
Way 1: 1 Loonie ($1.00), 3 Quarters ($0.75), 1 Dime ($0.10), and 1 Nickel ($0.05).
*
Way 2: 1 Loonie ($1.00), 1 Quarter ($0.25), 6 Dimes ($0.60), and 1 Nickel ($0.05).
*(Note: There are many other correct combinations as long as they add up to $1.90).*
4. Jack's Movie
*
Step 1: Calculate the correct change.
* $10.00 (Paid) - $6.37 (Cost) =
$3.63
*
Step 2: Compare with what Jack received.
* Correct Change: $3.63
* Change Received: $2.63
*
Conclusion: The amounts do not match.
