Final answer:
Rachael's change after buying a $3.90 pie with a five dollar bill is calculated by subtracting the price of the pie from $5.00, resulting in a change of $1.10.
Step-by-step explanation:
Rachael bought a pumpkin pie that cost $3.90 and gave the cashier a five dollar bill. To calculate her change, you subtract the cost of the pie from the amount she gave the cashier.
Here's the step-by-step calculation:
- Write down the amount given to the cashier: $5.00.
- Write down the cost of the pumpkin pie: $3.90.
- Subtract the cost of the pie from the amount given: $5.00 - $3.90 = $1.10.
Therefore, Rachael's change will be $1.10.
