Final answer:
To calculate the change she will receive, subtract the cost of the apples from the amount she has and perform the calculation. In this case, the change she will receive is $1.189.
Step-by-step explanation:
To calculate how much change she will receive, we need to subtract the cost of the apples from the amount she has.
The cost of 8.9 pounds of apples is 8.9 * $0.99.
We can multiply these numbers to find the total cost of the apples.
Next, we subtract the total cost of the apples from the amount she has. Since she has $10, we can subtract the total cost from $10 to find the change she will receive.
The calculation would be: $10 - (8.9 * $0.99). Let's calculate:
$10 - (8.9 * $0.99) = $10 - $8.811 = $1.189. So, she will receive $1.189 in change.
