Final answer:
After totaling the cost of Janet's groceries ($10.70), the change she received from a $20 bill is $9.30.
Step-by-step explanation:
To calculate Janet's change from a $20 bill, we first need to calculate the total cost of her items. The given information lists the cost of several food items:
- 10 apples at $0.50 each equals $5.00.
- 12 bananas at $0.20 each equals $2.40.
- 2 bunches of grapes at $0.65 each equals $1.30.
- 1 pint of raspberries at $2.00 each equals $2.00.
Adding these amounts together gives us the total spent on groceries:
$5.00 (apples) + $2.40 (bananas) + $1.30 (grapes) + $2.00 (raspberries) = $10.70.
Now, subtract the total cost of the groceries from the amount Janet gave to the cashier:
$20.00 - $10.70 = $9.30.
Therefore, the change Janet received back from the cashier is $9.30.
